Bob, >> (citation from Prog-guide)
and the next sentence is what I cited. Just so that everyone knows that VSE is an excellent OP_sys- here is what happens: 4 // ASSGN SYSADAT,IGN F4-0004 1A43D INVALID LOGICAL UNIT SPECIFICATION. This is off-thread - but I like to share it. Now watch this- because I was already playing I tried something more: 4 // ASSGN SYSRLB,IGN F4-0004 1A87D ASSGN SYSCLB/RLB/SLB NO LONGER SUPPORTED. USE LIBDEF COMMAND Good 4 // ASSGN SYSCLB,UA F4-0004 1A87D ASSGN SYSCLB/RLB/SLB NO LONGER SUPPORTED. USE LIBDEF COMMAND Good 4 // ASSGN SYSCLB,IGN F4-0004 1A04D INVALID I/O ASSIGNMENT. Oups- someone did not apply the complete correction- This is gone since 20 years. -- Martin Pi_cap_CPU - all you ever need around MWLC/SCRT/CMT in z/VSE more at http://www.picapcpu.de
