SOUL $functions

Some operations are inefficient or impossible to code in a high-level programming language like SOUL. To overcome this difficulty, SOUL provides a variety of $functions. Many of these functions are deprecated in favor of an OO API method. When that is the case, the $function page notes the matching method.

The mathematical $functions, and those $functions central to a Model 204 product (and which require authorization of that product) are listed separately; you can find links to those sets of $functions in the following table:

$Function set	Description
$xxxmath	Mathematical $functions
$Fact_xxx	SirFact $functions
$Ftp_xxx	Janus FTP Server $functions
$Sock_xxx	Janus Sockets $functions
$Web_xxx	Janus Web Server $functions
Sir2000	Sir2000 User Language Tools $functions

List of standard $functions

The following table lists available SOUL $functions, in alphabetical order. The list is not exhaustive (see the table of other $function sets, above).

Note: Some of the $functions listed below are only available with the purchase of a Model 204 add-on product. The individual page containing such a $function's full description has an itemized list of the add-on products that authorize the use of the $function.

Using functions

You can use functions in several ways, including, as a term in:

• An expression in a variable assignment statement, for example:

%X=$EDIT(2573,'99999')

• The specifications in a PRINT statement

A PRINT statement can include a function call anywhere a field name can be used. For example:

PRINT $EDIT(2573,'99999')

• An expression in a conditional statement, for example:

IF $EDIT(2573,'99999') EQ 02573 THEN...

• An expression which serves as the argument to another function, for example:

%L=$LEN($EDIT(2573,'99999'))

The direct use of function calls in some statements, such as FIND, results in compilation errors.

Comparing successful and unsuccessful $function code

If your request is coded as follows:

BEGIN $EDIT(2573,'99999') END

The following error is your result:

*** 1 M204.0229: INVALID STATEMENT $EDIT(2573,'99999')

However, if you code your request as follows, it works properly:

BEGIN PRINT $EDIT(2573,'99999') * Or * * %X=$EDIT(2573,'99999') * END

Function return values

Each function returns a single value to the calling request. For example, this function sets %A equal to the user's login account name:

%a = $account

This function causes the length of the current value of the FULLNAME field to be compared to 10:

IF $LEN(FULLNAME) GT 10 THEN . . .

Function arguments

Some functions require one or more arguments which allow you to pass information to the subroutine. Some functions take no arguments. Arguments must be enclosed in parentheses and separated by commas. For example:

IF $READ('CONTINUE?') EQ 'YES' THEN . . . %X = $mod(COUNT IN CT, %BASE)

Rules for function arguments

Function arguments follow the normal rules for arithmetic expressions. Arguments can include other function calls and can perform any type of computation. See the section Expressions for detailed information on expression syntax.

Argument evaluation and conversion

Model 204 evaluates each argument to a function as either a string or a number. When this data type conflicts with the data type required by the function, the following rules apply:

• If an argument is expected to be numeric but is a string, Model 204 converts the string to a number according to the conversion rules described in the assignment statement discussion in Relationship between %variable assignment and declaration and Conversion.
• If an argument is expected to be a string but is numeric, Model 204 converts the number to a string.
• If the original number contains decimal places, they are lost during the conversion.

User-written functions

In addition to the functions provided by SOUL, some customer sites write their own functions based on their particular needs. Before using any user-written functions, make sure that your site's FUNU module has been reassembled with the macro library supplied with the current release. Also, please be sure to carefully test your user-written functions before your system goes into production.

Notes:

• It is recommended that all user-written functions use the STMG/LMG Assembly Language instructions to save and restore any registers that are modified.
• The RESULT macro does not work in Model 204 Version 5.1 and later. Change any use of the RESULT macro in $functions to use the standard LEAVENUM, LEAVEF0 and LEAVESTR macros.
• In addition to the above considerations, see the installation instructions relating to FUNU.

Customers are individually responsible for any functions they write. Rocket Software takes no responsibility for user-written functions or their documentation.
