This page summarizes SOUL syntax and conventions, which are discussed in more detail throughout this wiki. The SOUL statements are listed in alphabetical order. Many of the section titles or syntax blocks contain links to the wiki page describing the statement or syntax phrase. A later section provides other SOUL syntax information, including links to information about the "tokens" of SOUL, such as names in SOUL.
All SOUL statements can be used between a Begin (or More) command and an End statement.
External Call Facility (ECF) statements are listed under External.
Various other Model 204 commands also have effects on the results of a SOUL request.
The following notations prefix some of the statements in the presentation of the SOUL syntax:
* ** + ++ C
See the notation conventions section for an explanation of these usages, as well as other general comments about understanding the syntax of SOUL.

Other syntax
Names, numbers, literals, comments
- Names (for example, %variables, labels): see Model 204 naming conventions
- Other constructs: see Basic request structure (which also discusses some rules for statement labels)
Value specification syntax
For all User Language statements and retrieval conditions, wherever the term value appears in the syntax, it can be any of these:
- Literal number or string
- VALUE IN clause of the form:
VALUE [IN] label
- %variable
Retrieval condition syntax
A Find or For Each Record Where statement can be followed by any number of retrieval conditions separated by an end of line or LINEND parameter character.
Conditions can be constructed as follows:
Syntax
[Not] phrase [{And | Or | Nor} [Not] phrase] ...
Where:
phrase can be constructed as follows:
- fieldname = [Not] value
- fieldname Like pattern
- fieldname Is [Not] {Present | Like 'pattern'}
- fieldname Is [Not] {[Numerically | Alphabetically]
[Eq | = | Ne | ¬= | Greater Than | Gt | > | Less Than
| Lt | < | Le | <= | Ge | >= | Before | After] value} - fieldname Is [Not] {[Numerically | Alphabetically]
{In Range [From | After] value1 {To | [And] Before}
value2 | Between value1 And value2} - Files filename
- Find$ label
- List$ listname
- Location {location | =}
- Point$ value
- Sfge$ value
- Sfl$ value
- A literal number or string
- Value {(expression) | [In] label}
- A %variable
where value can be:
Notes:
- The first character (
¬
) of the "not-equal" test (¬=
) in the fourth of the items in the list above is the EBCDIC "not sign," which has the hexadecimal value5f
. - For a description of the pattern in the [Is] Like and Is Not clauses, see the syntax of Is Like patterns.
Omitting repeated first words
If a sequence of phrases in a particular retrieval condition all have the same first word, that word can be omitted from the latter phrases. For example:
List$ A And Not List$ B
can be written:
List$ A And Not B
And:
x Is 13 Or x Is Less Than 7
can be written:
x Is 13 Or Is Less Than 7
Omitting duplicated equal signs
Duplicated equal signs can be omitted. For example, the expression:
a = 3 Or a = 5 Or a = 40
is equivalent to:
a = 3 Or 5 Or 40
Use of parentheses
Parentheses can be placed around any sequence of phrases to clarify the condition or force the evaluation to occur in a particular order. For example:
Not (a = 2 Or List$ y) a = 1 And (b = 2 OR c = 3)
Use of expressions
Expressions can be used in Find and For Each Record statements to provide the retrieval condition for the Point$, Sfl$, and Sfge$ conditions, as well as for the Eq Value clause:
Point$
Point$ Value(expression)
Where:
expression is a function call, string concatenation, arithmetic operation, SOUL construct, or Boolean expression. It is preceded by the keyword Value.
Example:
This example finds the first MA
record on file, and then counts the number of records from this point in the file:
FD1: IN ICSCUST FPC STATE = MA END FIND FOR 1 RECORD IN FD1 PRINT 'CURREC = ' WITH $CURREC PRINT '>= POINT$' FD2: IN ICSCUST FPC POINT$ VALUE($CURREC) END FIND END FOR
Sfl$ and Sfge$
Sfl$ Value(expression)
Or:
Sfge$ Value(expression)
Where:
expression is a function call, string concatenation, arithmetic operation, SOUL construct, or Boolean expression. It is preceded by the keyword Value.
Example:
FOR %CT FROM 1 TO 10 IN EXPRESS STORE RECORD ($EDITN(%CT,'999')) ORD1 = (%REC WITH %CT) ORD2 = (%CT * 2) ORD4 = (%CT * 4) END STORE END FOR COMMIT FOR %CT FROM 1 TO 5 PRINT 'LESS THAN ' WITH %CT FD1: IN EXPRESS FPC SFL$ VALUE($EDITN(%CT,'999')) END FIND PRINT 'GREATER THAN OR EQUAL TO ' WITH %CT FD2: IN EXPRESS FPC SFGE$ VALUE($EDITN(%CT,'999')) END FIND END FOR
Eq Value
fieldname Eq Value(expression)
Where:
expression is a function call, string concatenation, arithmetic operation, SOUL construct, or Boolean expression.
Example:
FD: IN FILE PEOPLE FD LAST EQ VALUE($READ('LAST NAME?') ) END FIND
Print specification syntax
A Print, Set, Audit, or Trace statement contains print specifications of the following form:
[term] [And | Tab | With]...[[term] [And | Tab | With] ...] ... [...]
Where:
term can be constructed as follows:
{'string' | %variable | Count In label | Occurrence In label | Value in term | function} [At [Column] m] [To [Column] n]
Or, if the statement is within a record loop:
{{Each | term} fieldname | *Record | *Id} [At [Column] m] [To [Column] n}
Note: For additional Print statement details regarding multiply occurring fields and field groups, see Print and Print n statements for fields.
Expression syntax
The following syntax can be used in:
- Assignment statements
- Conditional If statements and ElseIf clauses
In the simplified syntax for an If statement, which is:
If condition Then statements
condition expands to the syntax described in this section.
- Computed Jump To statements
- Subscripts
- Function arguments
Syntax
{operand | (expression)} [operator {operand | (expression)}] ...
Where:
- operand can be constructed as follows:
[+ | - | Not] {'string' | %variable | number | fieldname [(subscript)] Is [Not] Present | Count In label | Occurrence In label | Value In label | function}
- expression (Note: enclosed by parentheses) is a function call, string concatenation, arithmetic operation, SOUL construct, or Boolean expression. For further details, see Expressions.
- operator may be one of the following:
+ = EQ And - ¬= NE Or * > GT With (Note: this can also be achieved via Implicit concatenation) / < LT Is [Not] Present (Note: applied either to a field or to an optional or default method parameter) >= GE Is [Not] Like <= LE Notes:
- The first character (
¬
) of the inequality test above is the EBCDIC "not sign," which has the hexadecimal value5f
. - For a description of the
Is Like
andIs Not
clauses, see the syntax of Is Like patterns. - For more information about operators, see Operators.
- The first character (
In clause syntax
The SOUL statements on this page whose syntax display is preceded by an asterisk (*) support an In clause.
The three basic forms of the In clause are:
In [Permanent | Temporary ] Group groupname Member [%member | [filename [At {location | =}]]
In file1 [,file2] ...
In {$Curfile | $Update}
The form In $Curfile can be used only within a record loop.
In Group Member limitations
In addition to the three basic forms of the In clause shown above, the In Group Member clause restricts the following statements to one member file in a group context:
- Clear List
- Find All Records (and its variants)
- Find All Values
- For Record Number (or FRN)
- Store Record
You cannot use an In Group Member clause with a For Each Record statement or with an Add, Change, or Delete Record statement. Only the previously listed statements call accept an In Group Member clause.
Using an In clause in a Begin...End block
The file name in the In clause used within a Begin...End block is resolved by the compiler. You can hard-code a file name or use some type of dummy string for the file name. Using a %variable for the file name is not allowed.
Subscript syntax
A subscript has the format:
Syntax
(subscript1 [,subscript2 [,subscript3]] )
Where:
subscript1, subscript2, and subscript3 can be any expression.
Terminal display attributes
One or more of the following terminal display attributes can replace the term attribute in a full-screen formatting statement, if the display attribute is supported by the installation:
BLINK |
BLUE |
BRIGHT |
DIM |
GREEN |
INV[IS[BLE]] |
NOBLINK |
NOREV[ERSE] |
NOU[NDER]SCORE |
PINK |
PROT[ECTED] |

YELLOW |
Notation conventions
This page uses the following syntax notation conventions:
Syntax notation | Indicates that... |
---|---|
Single asterisk (*) | Statements can be preceded by an IN clause, if there is no reference to a previous set (label or list). See IN clause syntax for more discussion. |
Two asterisks (**) | Construct can appear only within a record loop. |
Plus sign (+) | Construct requires the optional Horizon feature. |
Two plus signs (++) | Construct requires the optional User Language to Database 2 feature. |
C | The syntax applies to a Model 204 command as well as a SOUL statement, except any %variable options or clauses.
Model 204 commands are listed alphabetically and documented in List of Model 204 commands. |
Lowercase italic | Constructs are replaced with variable information. |
- A field name (%%) variable can be used anywhere fieldname appears. The %%variable can contain its own subscript, separate from the field name subscript.
Note: The subscript of an array element must be specified before a field name subscript.
- The lowercase constructs — retrieval-conditions, print-specifications, expression, subscript, attribute, and type — are discussed separately following the syntax summaries, beginning with Value specification syntax.
- For more Model 204 notation conventions, see Notation conventions.
