Question:
Can an IPC VLS file library be tersed in order to binary FTP the tersed file to Support?
Answer:
No. IPC VLS files cannot be tersed as they are their own unique library file system that are accessed via BDAM. 

Attempt to terse as VLS library ...
//TERSE  EXEC PGM=AMATERSE,PARM='PACK'
//SYSPRINT DD  SYSOUT=*                              
//SYSUT1   DD  DISP=SHR,DSN=vls.library.input 
//SYSUT2   DD  DSN=terse.dsn.output, ...      
//SYSIN    DD  DUMMY


.. will result in error AMA522E and RC 10:     
** AMA572I STARTING TERSE ENCODE   PACK         16:33:01  01/08/2019 ****  
** AMA527I  INPUT  - DDNAME : SYSUT1   DSNAME: vls.library.input    
** AMA522E  INPUT DATA SET HAS AN UNSUPPORTED DATA SET ORGANIZATION        
** AMA573I TERSE COMPLETE ENCODE   PACK         16:33:01  01/08/2019 ****  
** AMA504I  RETURN CODE: 10                                                 


Instead provide a VLSUTIL BACKUP of the VLS file. Then terse the BACKUP if desired. Then binary FTP the tersed BACKUP.
