Since you said you wanted to improve your REXX skills, let me add the following
(I'm aware you might already know this):
>KEY = '**'
>CSIFILTK = SUBSTR(KEY,1,44)
...
>CSICATNM = SUBSTR('<catalog name>',1,44)
You might wonder why the CSI* variables are filled using the substr() function.
There is a special behavior of substr(), left(), right() in REX that I haven't
seen in other languages (and have indeed been missing there): If the source
string is *shorter* than the target length specified in the function call, the
source string is paded with blanks to make the result a string of the desired
length.
You can even decide to use a different padding character: All of these
functions allow an additional parameter, telling it the padding character to be
used.
