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

//JOBCARD
//STEP1 EXEC PGM=TAPEMNGL
//SYSUT2 DD UNIT=tape,
// VOL=SER=tapeno,DISP=OLD

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:

//JOBCARD
//STEP1 EXEC PGM=TAPEMNGL,PARM=MAPD
//SYSUT2 DD UNIT=tape,
// VOL=SER=tapeno,DISP=OLD

The additional information obtained with this JCL includes:

• directory listings for libraries unloaded with IEBCOPY, PANVALET, IEHMOVE, the Connecticut Bank and Trust compress utility or CMS, and for SMP and PUT tapes.
  
• facts about variable length and variable blocked files.
  
• data sets and/or mini-disks dumped with FDR, DS/DSF or the VM dump utility.
  
• facts about files unloaded with IEHMOVE.
