Statement syntax

Overview

This topic summarizes User Language syntax and conventions, many of which are also discussed throughout this manual.

The statements are listed in alphabetical order. Later sections in this topic provide other User Language syntax information.

All of the User Language statements listed can be used between a BEGIN (or MORE) command and an END (or END MORE) statement.

All system control commands are presented in the List of Model 204 commands.

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 User Language statement, except any %variable options or clauses. Model 204 commands are listed alphabetically and documented in List of Model 204 commands.
Lower case 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 lower case constructs — retrieval-conditions, print-specifications, expression, subscript, attribute, and type — are discussed separately following the syntax summaries, beginning with Value specification syntax.

Value specification syntax

For all User Language statements and retrieval conditions, wherever the term value appears in the syntax, it can be:

• Literal number or string
• VALUE IN clause of the form:

VALUE [IN] label

• %variable

Retrieval condition syntax

A FIND 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 < | <= | 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 LISTS$ listname LOCATION {location | =} POINT$ value SFGE$ value SFL$ value

where value can be:

Literal number or string

VALUE {[IN] label} | (expression)

%variable

Notes:

• The first character (,) of the inequality test above is the EBCDIC "not sign", which has the hexadecimal value 5f.
• 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

Moreover, 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 statements to provide the retrieval condition for the POINT$, SFL$, and SFGE$ conditions, as well as for the EQ VALUE clause.

POINT$

Syntax

POINT$ VALUE(expression)

Where:

expression is a function call, string concatenation, arithmetic operation, User Language 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$

Syntax

SFL$ VALUE(expression)

or

SFGE$ VALUE(expression)

Where:

expression is a function call, string concatenation, arithmetic operation, User Language 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

Syntax

fieldname EQ VALUE(expression)

Where:

expression is a function call, string concatenation, arithmetic operation, User Language construct, or Boolean expression.

Example

FD: IN FILE PEOPLE FD LAST EQ VALUE($READ('LAST NAME?') ) END FIND

 

Print specification syntax

A PRINT, SET or AUDIT statement contains print specifications of the following form:

Syntax

[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 label | function} [AT [COLUMN] m] [TO [COLUMN] n]

or, if the statement is within a record loop:

{{EACH | n} fieldname | *RECORD | *ID} [AT [COLUMN] m] [TO [COLUMN] n}

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. Be sure to enclose an expression with parentheses.

• 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}

and operator may be one of the following:

+	=	EQ	AND
-	,=	NE	OR
*	>	GT	WITH
/	<	LT	IS PRESENT
	>=	GE	IS NOT PRESENT
	<=	LE	IS LIKE
			IS NOT LIKE

Notes:

• The first character (,) of the inequality test above is the EBCDIC "not sign", which has the hexadecimal value 5f.
• For a description of the IS LIKE and IS NOT clauses, see the syntax of Is Like patterns.

IN clause syntax

Statements preceded by an asterisk (*), beginning with User Language statements, support the IN clause.

The three basic forms of the IN clause are:

Syntax

• 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 either hard code a file name or use some type of dummy string for the file name. The use of 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:

List of attributes

DIM

INV[IS[BLE]]

NOU[NDER]SCORE

Type syntax for the DECLARE SUBROUTINE statement

The type specification for the DECLARE SUBROUTINE statement has one of the following formats:

{STRING [LEN n] [DP {n | *}] [ARRAY (*[,*[,*]]) [NO FILE SAVE]] | FIXED [DP n] [ARRAY (*[,*[,*]])] | FLOAT}

or

[LIST] [IN [FILE | [PERM | TEMP] GROUP] name]
