I was told that the REXX codes should be placed in a special attribute library as follow:
Record format . . . : VB Used blocks . . . . : 4
Record length . . . : 255 Used extents . . . : 1
Block size . . . . : 19069 Used dir. blocks . : 3
1st extent blocks . : 4 Number of members . : 13
Secondary blocks . : 2
Data set name type : PDS
I was planning to put my REXX code in a PDS in which if FB and 80 as record length.
