Processing Functions for Character-Like Arguments

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 symbol 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 boolc function also belongs to these functions, however here it is treated according to its role as a logical function.

Other versions: 7.31 | 7.40 | 7.54

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.
