Jol has a number of way to get data into Symbolic Variables.

When operating under TSO, Jol can:
1. Use the READ instruction to ask for a simple line of input into a 
Symbolic Variable.
2. Use the Full Screen Structured 3270 to read a fullscreen into a 
number of Symbolic Variable3.
3. Use the Alloc File instruction, the Read File(x) into (y) instruction 
to read the contents of any file.

4. Create a Card Image file any symbolic variable.

Sourceline() is a common approach to what I think you mean by instream
data. It's often used to keep Help data within the exec.


Indeed, I've used it that way.  It saves many keystrokes compared to
individual QUEUE, EXECIO, or compound symbol assignments.  It lacks
facility to substitute symbols.

CMS/TSO Pipelines (remember, it's embedded in Rexx) provides the
alternative BEGOUTPUT; the Ref. uses the term "implied output mode"
describing it.

Wouldn't it be nice to have something like "ADDRESS DD:SYSUT2"?

Re: John's spare time ... Job Scheduler Programmer Architect?


Jol has an inbuilt calendar. Therefore, it is easy to do this.  Just code:

   Submit Jol.job(%day);

You could also have a full Jol procedure, and in it have code similar to:

  If %day='FRIDAY'
  Then do;
   .
   End;

Paul,

I am not sure why DFSORT is dragged into this topic, but you don't have to
code dozens of DFSORT commands. I always believe in using the right
utility for the job. Scheduling jobs is not something DFSORT can process,
however it can handle simple requests. Here is a sample to submit a job
based on the day of the week. we can validate the date and time too.

I'm aware that it's there, although only recently (from my perspective).
I don't know that it meets all the requirements of a job scheduler.

And some readers of this list still prefer not to deal with UNIX.  But
I guess that's a personal problem.

Re: John's spare time ... Job Scheduler Programmer Architect?

1. Jol has the ability to read and write files with PL/I or Clist style
statements.

For example:

ALLOC F(INPUT5) SYS1.CONTROL.LIB(%DAY) SHR ;
/* Opens member depending on the day */

OPENFILE INPUT5 INPUT; /* Open the file */
IF ^ EOF(INPUT5) THEN
READ FILE(INPUT5) INTO(A);
further processing

2. Jol can read directly from the TSO terminal with the simple READ
instruction, or use a full screen 3270 input with structured fields,
Menu Bars and Pulldown style menus. See the Panel instruction.

http://www.members.iinet.net.au/~mitsu2/JolWebManuals/INS_Panel.html

The 3270 Screen on the Jol Home Page was created with the Panel
instruction. View it here: http://start.oscar-jol.com/home

3. Symbolic Parameter or Variable substitution is available in any Jol
Command.

Jol has most of the inbuilt functions of PL/I. SUBSTR, and so on.

See description at
http://www.members.iinet.net.au/~mitsu2/JolWebManuals/GDE_Compile%20Time%20Facilities.html

4, Jol can create SYSIN card files with SYMBOLIC Variables replaced. So
it is possible and easy to create utility control cards from Symbolic
Variables.

See Declaring Card Image Data Sets here:
http://www.members.iinet.net.au/~mitsu2/JolWebManuals/RefGuide_With_Frames.html

Re: John's spare time ... Job Scheduler Programmer Architect?

Jol has a builtin sort.  The following code can be executed in Batch or 
directly under TSO.


   DCL DSID1 DS PAYROLL.TRANS.FILE;
   DCL DSID2 DS PAYROLL.SORTED.TRANS
VB 300, 8000
10 CYLS DISK;

SORT DSID1 TO DSID2
FIELDS=(
10,2,CH,A,/* COMPANY CODE */
25,5,FI,A);/* STATE CODE */

The data set referred to by DSID1 is to be sorted and placed in the data 
set referred to by DSID2. The parameters for the SORT are specified 
using the FIELDS parameter.


Of course, you could code it as

SORT PAYROLL.TRANS.FILE TO PAYROLL.SORTED.TRANS
FIELDS=(
10,2,CH,A,/* COMPANY CODE */
25,5,FI,A);/* STATE CODE */

One could argue that DFSORT is superior due to it's extreme efficiency.
Especially compared to "grep". But that only applies when one is running it
in "heavy demand" situation. IMO, a slightly better case would be writing
something in "awk" versus REXX. IMO, for an "ad hoc", awk might possibly
beat REXX, if the programmer knows both. But only if the Co:Z hybrid batch
product (free from Dovetailed Technologies!) is installed. I wish that IBM
would license & bundle Co:Z with z/OS. That would increase it's legitimacy
to staid I.T. managers.

I have sorted Rexx stems using calls to omvs sort before. It was a long

The link references the Unix command, cron, that runs under Unix System 
services, so you can schedule Unix commands, which could issue JES2/STC/TSO... 
commands from there.

Personally I recommend SCHEDRUN from the CBT Tape, which uses JES2 auto

(E.g coding dozens of lines of DFSORT commands where a single
