CHAR Function
CHAR Function
The CHAR function returns the character value of a specified position in the ASCII
collating sequence.
n
is an integer expression with a value from 0 through 127.
Considerations
•
The CHAR function result is always type character*1.
•
The value of CHAR (n) is undefined for argument values of
n ≤ 0 or n > 127
•
The CHAR function is the inverse of the ICHAR function.
•
The ASCII collating sequence is given in Appendix A, ASCII Character Set.
Examples of the CHAR Function
The following example returns a value of “Z” for LETTER and a value of “#” for SIGN:
CHARACTER letter, sign
letter = CHAR (90)
sign = CHAR (35)
CMPLX Function
The CMPLX function returns the complex value of any numeric type.
x
is an expression of integer, real, double precision, or complex type. See
Considerations.
y
is an expression of integer, real, or double precision type.
