Note: IBM recommends that you do not use the TRIM function on dynamic arrays.
For BASICTYPEs M and P, some leading and trailing spaces or occurrences of a
specified character are not removed from elements in a dynamic array. For example,
for BASICTYPE M or P, the following program segment:
P = “**Fred**Smith**”:@VM:”**Jim**Olsen**”
Q = TRIM(P,”*”)
produces the following result (notice the asterisks surrounding the delimiter
character):
Q = Fred*Smith*}*Jim*Olsen
For BASICTYPE R or U, the program segment produces the following result:
Q = Fred*Smith}Jim Olsen
To get this latter result regardless of BASICTYPE, use the TRIMS function.
Examples
In the following example, the program segment removes the leading, trailing, and
extraneous blanks from the variable NAME:
NAME = " Zenith, R. "
NAME = TRIM(NAME)
This results in the following:
NAME = "Zenith, R."
In the next example, the program segment removes the asterisks from the variables
X and Y:
X = TRIM("***NOT***ICE***","*")
Y = TRIM("***NOT***ICE***","*","A")
This results in the following:
X = "NOT*ICE"
Y = "NOTICE"
