ok. this is strange one.
I run a basic rexx program. (batch, if it matters).
| Code: |
/* rexx */
say "hello rexx!"
return 0
|
and i get -
wonderful!
than, i add a few more "say" lines..
| Code: |
say "line 2"
say "line 3"
say "line 4"
|
now the question is -
say i want to put the cursor back
at the start of the first "hello rexx!" line,
and i want to rewrite that line.. is there a way to do it?
I have tried the
ADDRESS ISREDIT "(ROW,COL) = CURSOR"
approach. didn't work.
(based on this -
and a few others similar)
I have tried the
| Code: |
| address ispexec "VGET (ZSCREENC ZSCREENI)" |
approach, which worked, but still couldn't get the csr position,
or to move it.
I'm not talking about a panel.
just a basic output. instead of writing to the next line,
write OVER the same line.
My questions are -
1 - is it even possible?
2 - if so, where could i find a reference?
Thanks,
me. |

re: My questions are -

No, it is not possible. The 3270 terminal has two modes: line mode or full screen mode. You can switch between the two, but it seems that you want something in-between.
The SAY operates in line mode, whereas that ISPEXEC stuff is going to be in fullscreen mode.
Since you are using rexx, you can use OUTTRAP to capture the linemode output then display that later in fullscreen mode via ISPF... you can then have some control over what is shown and cursor placement. |

Thanks for the reply sir.
I indeed aimed for something in between,
Trying to save myself the trouble of writing
panels just to pretty-fy my debug/user msgs.
Much obliged.
I also get it that it means that say is full line,
So I can forget about using strings with break-lines in
The middle, and than throwing them to a say debug-msg proc..
Oh well.. all part of the adaptation curve from open, to mf.
(Going to build a small pretty pop-up debug msg sys just
To get comfy with panels. )
Thanks a lot !! 🙏 |

You certainly can't do it in batch.
For online then most sites have a CLEAR or CLEARSCR command so you can do one SAY, then clear the screen and do the next SAY and so on. |

re: in batch
As I said earlier, you can use OUTTRAP to capture the line mode output. Create a separate exec that starts the trapping, then have it call your problem exec.
When the problem exec ends, you can stop the trap and process the lines and manipulate them in any way that you want, and finally write the results to the SYSPRINT file. |

Throughout this whole string, the OP has not really stated what he is trying to achieve with this exercise.
He/she talks about batch, isredit commands, ispexec commands, pop-up panels.
Kind of all over the place.
Just saying |

Lol.. it doesn't.
Just to be sure I've also tried the ascii one,
The different '/n' version, and the `n version..
U guess I could hack it with some asm,
But.. it wasn't designed for that
Its my way of thinking that requires adjustment,
Not the code. Adapt to it. Don't fight it.
Re: Or you could just use two SAY statements
In the "open", what we would do is to run a basic
Debug proc with juat a printout cmd, hold an error msg enum
Table, and just "call dbg_msg 2134". So the inline /n was
Used as a pretty quick and dirty way to arrange the data
And add extra info.
I just need to re-adjust my conceptul thinking around
The MF, 3270 and the whole.. way of thinking.
Was fun trying though 😅😁
Again - thanks a bunch 🙏❤ |

In dbg_msg, split up the message text:
| Code: |
parse arg part1 '/n' part2
say part1
say part2
