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
.
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.
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.
