There is always some historical reason that IBM would create a library with the FB/80 attribute. Gilbert is right i remember this also and we had problems when trying to concatenate a VB/255 Clist library. So most folks stuck with FB/80...

In 1980, the SPF FDP which was 5787-XT2 (Structured Programming Facility) became the SPF product 5668-009 (System Productivity Facility), installed under SMP, which does not support a PDS with RECFM=VB. The vast majority of CLIST/REXX libraries are defined with FB/80. Before you define one with VB/255, remember that you can NOT concatenate it with existing FB/80 libraries. Of course, it would be nice if concatenated CLIST/REXX libraries could be FB and VB, but I'm not sure IBM will make it possible in the future. Most of my products use the GETSEQ/GETDIR/GETMBR run-time routines which allow the concatenation of sequential and partitioned data sets with different DCB attributes. If I do it, IBM could do it also. -- Gilbert Saint-Flour GSF Software http://gsf-soft.com/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
