RE: Re: SixPacks mods for GCIC users

Paolo

Couple of points here.

1) You should really be proud of yourself -- I think its no easy task to
waddle thru that mess of code in the GSVC module. I am really surprised that
you are managing to navigate thru all of that as well as you seem to be
doing.

You appear  to be have no problems and I guess that’s the result of Many
years of experience. I hope you are enjoying it.

2) I know it's a very complicated piece of logic without much documentation
And it handles all the interrupts - devices, timers, task waits, enquing of
tasks and of course all the storage control. As well as abends etc.
And other stuff like time slicing and accounting. Probably a lot more.

3) All of your fixes in this last round sound great and won't interfere with
the overall logic of the GSVC or the EDIT application. Or any other
application that I/we will build on that.

This is the right place to make those kinds of changes.
For the next version of the editor I would like to get rid of the sign-on
screen.

If you have time take a look at that module and maybe you can just branch
over that code directly to the FLIST screesns.

4) When you are finished, send me the Final source(s) and I'll check it out
and put in the next release.(whenever that may be)

Forgive me for not having much time right now, but my head is in the MVS
version.

I am pushing away at the "MVS" code, and my brain is busting from strugggles
with the environment. I am using TSO native - no REXX routines - no "C".

Also have some personal issues.... Somebody wants to give me a JOB - and
wife is pushing me to take it. Lots of $$$$ but on the wrong continent.
Keeps me up at night. I was just beginning to enjoy being retired.
I'd love to pass it off to somebody, but you have to be a fluent "HEBREW
SPEAKER" as well as ENGLISH. Anybody with 35 years experience would be
qualified.

Back to MVS.

Have most of the major problems worked out. The editor and the BROWSER wont
need much fixing once I get the IO and the calls to TSO working.

Right now I am struggling with the FLIST equivalent. I don’t have that nice
LISTF function and a easy way to catch the console output  as I did in VM.

I am using LISTC and then CAMLIST to get the information and it's taking me
forever.

The disk IO also is not FSREAD and it’s a lot more comlicated. With DCB's
and DYNAMIC allocates. Screen-io is a breeze and I modified my mapping
routines to work with that.

But I am past most of the big issues and I can start pretty soon on the
BROWSER itself.

Goes to say that I am not devloping it on MVS5 but I will retrofit.
Sticking to mostly basic functions that I hope existed back in the
pre-historic days.

Might need some help moving the files and finding the proper libraries to
put everything (SYSPROC for the execs and I'll have to define a new library
for the load module or add them to one of the libraries out there.)

ANYBODY who can help with the real MVS5 environment, even just suggestions
on how to move the data and to where, I will aprreciate that.
Should be ready for that in about a week or ten days.


Paolo ----
Have you been using the IND$FILE routines? Any problems wth that?
Still time to make fixes for in that for the MVS version.
