Yes. There are some programs to around to take CMS ?€?tape dump?€?
files and extract the files
I think the problem with tape dump files is either they are specific to a
version of CMS or they are specific to a disk filesystem (ie EDF or non-EDF).
Whichever it is, the result is that it is very easy to end up with a tape dump
format tape which cannot be read by VM/370 CMS.
For text files containing records that are 80 characters or less wide, the
easiest approach is to use the "real" card reader and card punch. For
everything else, I prefer to use VMARC which is like Zip for VM. There is a
version installed on the Sixpack systems (as VMARC370). There is also a
version called VMA which can be compiled and used on the host system,
maybe with a little effort. Both can manipulate the same archive files in card
image format which can be sent through the reader and punch.
Have we already had this conversation recently?
I feel like it's deja-vu all over again :-)
