CA-7 Load :
Now we have finished creating the batch terminal input cards (BTI), we need to load these on to CA-7.

BTI Split and Check programs: 
The CA-7 program used to load in the BTI cards is called SASSBSTR. However, this program has two problems, firstly it is unlikely that it will be able to accept each file whole, we have just too many definitions here! So, the program PGMBS splits up each of our files into an number of sections. Once these bits are given to SASSBSTR we need to run the output through another program to check that all the definitions worked ok.

PGMBTCHK: 
Here is some of the output from PGMBTCHK. It details all the different codes found in the BTI output and more importantly, details any errors. The return code of this job is the number of errors it has found.
