I suspect that there was a system PROC that we were making use of.
Early S/360 JCL was pretty simple, particularly on the "downlevel" OSes
like DOS/360. A "load and go" FORTRAN job on DOS could be as simple as:
//JOB
//EXEC FORTRAN
...program source
/*
//EXEC LNKEDT
//EXEC
...data for program
/*
/&
On CDC SCOPE JCL was also pretty simple; the same job was roughly like
this. Note that the JCL for the entire job comprises the first data
record:
JOB card with octal time limit(!)
RUN(G).
7-8-9 card
source program
7-8-9 card
data
6-7-8-9 card
