Hello Howard,

As the information you supplied states, you need to read the Chapter on Backup 
and Recovery APIs in the 
System API Manual (SPIR).  

Create a program (language of choice) that accepts the four parameters 
described in the SPIR.  Add this 
program to the registration exit point described --QIBM_QTA_TAPE_TMS -- use the 
WRKREGINF (? hey, it's 1:00 
am here, give me a break!) command for this.  The primary intent of this API is 
for tape library programs to 
log SAV/RST information.  You will need to play with it a bit to see if you can 
get control when you need to.

Regards,
Simon Coulter.
