When I run a FAVER2 MAP pgm against this tape, I do not get a full 'Map' of all the DSN on this tape.. The program reads the first DSN ( and truncates the name to 17 characters)

Question:
 
Is there some kind of limitation on DSN creation?  The TLBL is truncated to 17 char.  Why the  FAVER2 MAP pgm only showing one DSN
 
/ JOB GVMAP2                                
*  ASSGN SYS001,702                          
// ASSGN SYSLST,SYS007                       
// TLBL COPYIN,'DSN.NAME.20151201'
// EXEC FAVER2,SIZE=AUTO                     
   MAP                                       

There are multiple files on the TAPE

 

Answer:

Yes there is a 17 char limit on the TLBL.

 

When there are multiple DSNs on a tape, a TLBL for each DSN must be present for each one.
