I saw that link to the VMSHARE stuff about those problems with PETAPE on newer VM versions -- a very good find!??

Do we have source code for PETAPE?

IIRC, when PETAPE first appeared, it was done as an UPDATE deck for DMSTAP -- the CMS-supplied TAPE command.

The VMSHARE discussion does include references to code, I have to look at any existing NOTE PETAPE and MEMO PETAPE to see what is hidden there.

On the WATERLOO6 tape see the abstract which has the following information. This might be the last, best version of it.

M0063V03P-E TAPE COMMAND-- Modifications to Perkin-Elmer's version of tape
command? for Release 6.? There is a new tape format consisting of an embedded
header? and blocksize of 16005 for tape records (use of 'BLKSIZE' option allows
user to specify blocksize up to 32005).? Also allows user to write tapes in PLC
format.? All IBM formats (old 800 byte and new 4096 byte formats),? old PE
format, and PLC tapes can be read, and they all can be written except? for the
old PE format.? Also, the tape command will consist of two modules.? For more
information about all the changes in the tape command see the?? document file.
There is tape command support for BSEPP and non BSEPP, based? on Release 6 PLC
