Processing Functions for Character-Like Arguments

ABAP - Keyword Documentation → ABAP - Reference → Processing Internal Data → Character String and Byte String Processing → Expressions and Functions for String Processing → String Functions →

The following processing functions have a character-like result. They can be declared at general expression positions and character-like expression positions. The return values have the type string.

cmax, cmin - character-like extreme value functions

condense - condense function

concat_lines_of - concatenation function

escape - escape function

insert - insert function

match - match function

repeat - repeat function

replace - replace function

reverse - reverse function

segment - segment function

shift_left, shift_right - shift functions

substring, substring_... - substring functions

to_upper, to_lower, to_mixed, from_mixed - case functions

translate - translate function

The function boolc also has a return value of the type string and is (in principle) also one of these functions. It is handled, however, in accordance with its role as a logical function.

Notes

The processing functions for character-like arguments ignore the trailing blanks for input parameters with fixed lengths.

The processing functions for character-like arguments cannot be used directly as operands of arithmetic expressions, but can be used as operands of descriptive functions.

The type string of the return values must be respected mainly when using functions in comparisons.
