I'm confused. What I see documented is that an ESD record in an object file has up to 3 18-byte ESD item, with the length for SD in bytes 16-18; a CESD record in a load module has 16-byte ESD items with the length for SD in bytes 14-16.
The RLD has adcon type 00 for A and 01 for V. -- Shmuel (Seymour J.)

However, I have done many things in my 47-year IBM mainframe career (mostly MVS -> z/OS, but with a smattering of VSE, VM, Fujitsu MSP, and even Hitachi VOS3). Currently I am working with a well-known debugging product. I am a voracious reader, and often test things out to fill in any gaps in my knowledge. * I am a 'lurker' on this (and other) list(s). I rarely post, but when I do it often starts something, which is a good thing. * I made a mistake in my previous posting about RMODE64. The ESD object records (and CESD load module records) do not have an 'add 4 to the length flag' In fact, object ESD entries do not have a length field at all. Sorry. Interesting, my testing has shown that you cannot tell the difference in the ESD between ' DC V(FREDV)' and ' EXTRN FREDX / DC A(FREDX)' or ' DC VD(FREDVD)' and ' EXTRN FREDX8 / DC AD(FREDX8)'. This would have ramifications for a disassembler. The ESD record has the assigned ESDID for those entries. * However, the 'add 4 to the length-1' flag *IS* in the object RLD (and, presumably, in the RLD for the load module). My testing shows that the 'add 4' flag is set for AD or VD constants. AD/VD constant RLDS have the assigned ESDID in them (so you can tie the RLD and ESD records together). * Yes, Paul, VD(XYZZY) is valid in the latest versions of HLA, and, as documented above, generates RLD entries with the additional length flag set.
