Just a few observations:
1) I suspect that the *USRSPC may be being created with a x'00' (null)
rather than x'40' (blank) initializer. Your RCRTUS *PGM would be
the place to check if this is true. If so, your compare should be
to *LOVAL rather than *BLANKS.
2) List APIs return the number of entries found in the *USRSPC generic
header entry at offset 133. By using this value to control the
loop you do not have to assume a given value such as *BLANKS or
*LOVAL to exit the loop. This generic header can be found in the
Programming Tips chapter of the System API Reference, and also
member QUSGEN of QSYSINC/QRPGSRC or QSYSINC/QRPGLESRC.
3) This program is hard coded with API values that may not always hold
true. Rather than always going to offset 513 (STRPOS) for the first
returned list entry the program really should find this offset value
in the *USRSPC generic header (offset 125) of the List API. Likewise,
rather than always adding 10 to STRPOS to access the next list entry
the program should really add the value found in the *USRSPC generic
header (offset 137) Size of each entry. By not hardcoding these
types of values, your program can become tolerant of format
expansions/changes (which do periodically occur).
If this program is just a one time shot, then you can ignore 2 and 3
above; but if this program is intended to run for the next umpteen
years and releases I would suggest using the above approaches for
processing the returned list.
