Hi Last weeks discussion on sorting a REXX stem inspired me to write a program to do it.
example call to sort ascending "ISPEXEC LIBDEF ISPLLIB DATASET ID ('my_loadlib') STACK" "ALLOC FI(SORTPRT) DUMMY" r_c = SORTSTEM(my_stem_name,'A') "FREE FILE(SORTPRT)" "ISPEXEC LIBDEF ISPLLIB " SORTSTEM gets the variable count from my_stem_name.0 and then looks at every variable in the stem to get the maximum length. Then it getmains some storage big enough for the maximum record plus 4 bytes for the length of the variable It then calls the system SORT passing E15 and E35 exits SORT FIELDS=(1,max_len,BI,A),FILSZ=stem_count OPTION MSGDDN=SORTPRT RECORD TYPE=F,LENGTH=(max_len+4) On each call to the E15 exit the next stem variable is read, padded with spaces and the length put on the end On each call to the E35 exit the variable is put back into the stem, starting at 1, using the original length It will be on File#953 of the CBT Tape soon, but it anyone wants a preview then the code is in IEBUPDTE format here http://www.spurtle.biz/STEMASM.txt and supporting macros here http://www.spurtle.biz/STEMMAC.txt You will need to assemble the six modules then link INCLUDE SYSLIB(STEMSORT) ENTRY STEMSORT Regards John ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
