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 .
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.
