BUILT IN FUNCTIONS IN RPGLE PDF

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.

For example, if the string contains the third character in fromevery occurrence of that character is replaced with the third character in to. When this function is evaluated for its value, it returns the current occurrence number of the specified data structure. For a graphic literal, the size is the number of bytes occupied by the graphic characters, not including leading and trailing shift characters. All three must have the same type. The length specified must be between 1 and By default, translation starts at position 1.

The value returned is in unsigned integer format type U. When any parameter is variable in length, the values of the other parameters are checked against the current length, not the maximum length.

For more information, see Memory Management Operations. If length is not specified then the substring continues to the end of the string.

For all other data types, the value returned is the number of bytes of the value. For now just think of a procedure as a kind of hybrid subroutine.

The converted value is returned as a timestamp. If the length of the right-hand side of the expression is longer than the specified length, the right-hand side value is truncated.

Built-in Functions

Doolittle’, if the search starts at position 2. If the parameter is a constant, the conversion will be done at compile time. Take our weekly poll. Adding or subtracting a number of years to a February 29 date may not be reversible. The converted value remains unchanged, but is returned in a format that is compatible with character data.

Float numeric operands are not allowed. The string can be character, graphic, or UCS-2 data. There is nothing special you need to do to use built in functions however. Otherwise, it is 23 characters.

Built In Functions

Otherwise, the result will be in decimal format fucntions a leading negative sign if the value is negative, and without leading zeros. The string must be character, graphic, or UCS-2data.

Data corruption will occur if both of the following are true: This is especially useful when building text strings as in: The result begins at the specified starting position in the variable and continues for the length specified.

The edit word must be a character constant.

Unindexed arrays are not allowed for start and length. Send mail to midware midwareservices. 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.

For numeric expressions, the value returned represents the precision of the expression and not necessarily the actual number of significant digits. Adding or subtracting a number of months to the 29th, 30th, or 31st day of a month may not be reversible. The fourth parameter is the starting position for translation. The result is varying length if the parameter is varying length. This length should be greater than the maximum length the right-hand side will have.

The third parameter specifies the unit.

The system knows the format of the input in this case. The function returns a pointer to the allocated storage. In most cases, the result of adding or subtracting a fuhctions number of months is obvious.

This built-in function can be used anywhere that an unsigned integer expression is valid. It may only be compared with and assigned to items of type basing pointer. The result is varying length if the parameter is varying length, or if the parameter bui,t single-byte character. For information on the input formats that can be used, see Date Data Type. 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 not specified, it defaults to These named constants can be used in any specification.

If the left-hand value is February 29 and the jn year is not a leap year, February 28 is used instead. This is illustrated in Figure The first parameter is the date, time, or timestamp value. For example, if a 5 character graphic field is converted, the returned value is 12 characters 10 bytes of graphic data plus the two shift characters.
