Mapping Capabilities

TAPEMNGL has many uses which range from mapping tapes (i.e. finding out what is on a tape), to listing and/or dumping (in hexadecimal, ASCII or OCTAL) data blocks, to copying and/or converting various tape formats, to recovering data from mangled or reused tapes.

With the following simple JCL

TAPEMNGL will give the user information on almost any tape that can be created on a computer. TAPEMNGL recognizes the usual standard label and no label tapes normally created on an IBM compatible main frame, however it also recognizes ASCII label tapes, tapes created on PDP, VAX and Honeywell CPUs, tapes created on DOS or VM systems, as well as tapes created using ATS, QL/ATS, PHOENIX and Coursewriter. TAPEMNGL can also distinguish files created using IEBCOPY, IEHMOVE, IEBUPDTE, the Connecticut Bank and Trust compress utility, PANVALET, FDR, DS/DSF, IEHDASDR, CMS, etc. Use the simple JCL given above and all of this will be revealed in a simple, easy-to-read map.

Additional data about the files on the tape can be obtained by executing a MAPD (i.e. a map with directories). To do this you would use the following JCL:

The additional information obtained with this JCL includes:
