I wish those of you not current on VSE would remember that we have had
just as many years to change things as z/OS has. Oh, wait, we have
longer. DOS came out before what ever MVS was called back then.
z/VSE has a lot of things in the JCL that z/OS has no equal to. I work
both areas and there are many things in z/VSE that I miss in z/OS. There
are also some things in z/OS that are not in z/VSE, but the last z/VSE
to z/OS conversion I did, the client programmers hated the 'limitations'
they found in z/OS and had to go do a lot of program changes due to
these limits.
Later, when I have time, I will list some of those things.

private extensions (and I've seem some of them).

My memories of VSE JCL are dated, and quite possbily incorrect with
current VSE, but I recall that I felt it was more complicated that MVS
jcl. It had more types of statements (although fewer parms per type),
JOB, * $$ JOB, UPSI, OPTION, LIBDEF, PAUSE, and EXEC statements. To
describe a disk file, potentially required at least 3 statements, ASSIGN,
DLBL, and EXTENT. Tape required ASSIGN and TLBL, tape, disk and inline
files were not interchangeable as far as programs were concerned.
An interesting 'feature' was that syntax checking was done at execution
time, so when a JCL error was encountered, a console message was issued
that required a reply, allowing you to retype the errant statement. So in
the days of real card readers, if you needed to make a quick one time
change to a job, you could just flip the card around backwards, causing
'Invalid Statement' console message prompt, allowing you to type in the
statement you really wanted.

How does z/OS JCL compare with VSE JCL? My memories of DOS360 JCL
probably are
irrelevant.
