ILE RPG Built-in-functions. %ABS – Absolute Value of Expression. %ADDR – Get Address of Variable. %ALLOC – Allocate Storage. %CHAR – Convert to. In addition, under OS/ V3R2 and V3R7 the %PARMS built-in function was introduced. Since then, several built-in functions have been added to RPG IV. ‘1’ if the most recent file input operation or write to a subfile (for a particular file, if specified) ended in an end-of-file or beginning-of-file condition.

If the start position is specified, the search begins at the starting position. If a start position is not specified, the search begins at position 1.

AS Training: Built-In Functions in rpgle

The first three parameters can be of type character, graphic, or UCS When the string parameter is varying length, the values of the other parameters are checked against the current length, not the maximum length. It cannot contain an expression, but some constant-valued built-in functions and constant expressions may be accepted.

A file is considered “open” if it has been opened by the RPG program during initialization or by an OPEN operation, and has not subsequently been closed.

The following units are valid: Float expressions are not allowed in the first parameter. If the value of the numeric expression is non-negative, the value is returned unchanged.

The value must be greater than or equal to zero, and less than or equal to the current length of the source string. When this function is evaluated for its value, it returns buily current occurrence number of the specified data structure.

It may be specified anywhere a numeric constant is allowed in the definition specification or in an expression in the extended factor 2 field. The left-hand value must be a date or timestamp. The edit word must be a character constant. Otherwise, status vuilt be set at run rpgl but no error message will be given. In general, the arguments of the built-in function are similar to the factor 1 and factor 2 fields of an operation code.


This length should be greater than the maximum length the right-hand side will have. This is the same as the error indicator being set on for the operation.

If the first parameter is a date, do not specify the second parameter. The precision of the result is the minimum that can hold the result of adding together all array elements, up to a maximum of 30 digits. The result is a date or timestamp value with the appropriate number of years added or subtracted. If not specified, it defaults to The starting position defaults to 1.

This built-in gives non-static native methods access to the class instance.

These named constants can be used in any specification. The argument may be a literal, a named constant, a data structure, a data structure subfield, a field, an array or a table name. When used with keywords, the operand must be a numeric literal, a constant name representing a numeric value, or a built-in function with a numeric value known at compile-time. The second parameter must be the same type as the first parameter.

The result is a date or timestamp value with the appropriate number of months added or builf. The second parameter must be a non-float numeric value with zero decimal places.

If length is not specified then the substring continues to the end of the string. Otherwise, the result is fixed length. Buiilt, if the search starts at position 2. For a hexadecimal or UCS-2 literal, the size returned is half the number of hexadecimal digits in the literal. Unindexed arrays are allowed for string, start, and length. In the second parameter, the edit code is specified as a character constant; supported edit codes are: The following example illustrates this.


For information on the input formats that can be used, see Time Data Type. The third parameter specifies the unit. The syntax of built-in-functions is: This function is illustrated in Figure There is nothing special you need to do to use built in functions however.

The first parameter must be a basing pointer value. Otherwise, this function returns ‘0’. Rpgel syntax of built-in functions is: If the length is not specified then the string is referenced to its end.

The search starts at index startindex and continues for numelems elements. The pointer must be set to point to storage at least as long as the length parameter. The length indicates the amount of storage that the pointer points to. If the value of the expression has a variable length, the value returned is in varying format.

For a multiple-occurrence data structure containing pointer subfields, the size may be greater than the size of one occurrence times the number of occurrences. If either operand is an integer numeric value, the result is integer. A non-static native method works on a specific instance of its class.

The string can be character, graphic, or UCS-2 data. The left-hand value must be a time or timestamp.
