QBR is a z390 program to create break point (AT) commands

Hey, new version. I like this one better. Simpler.

QBR was written to make TEST easier for me. I have ADD and fat fingers, and am 81 years old, and make way too many mistakes. So I use TEST a lot. I'd hoped that z390 would be modified to let me stack commands in the input line, and set several break points at the same time. That's not going to happen, but in addition to a list of all the breakpoints you want, QBR does create a series of breakpoints in one line, that fit on the z390 command line (you have to make it wider) and then you can set the breakpoints fairly easily. For example, put this output on the command line, hit enter, RETRIEVE IT WITH THE UP-ARROW (I never knew that worked) erase the first one and enter the second.

A FE4E0. A FE598. A FE636. A FE63E. A FE644. A FE66A. A FE670. A FE6D0. -paste, then enter, retrieve, erase and ...

A FE598. A FE636. A FE63E. A FE644. A FE66A. A FE670. A FE6D0. -enter, retrieve, erase and ...

A FE636. A FE63E. A FE644. A FE66A. A FE670. A FE6D0. -enter, retrieve, erase and ...

A FE63E. A FE644. A FE66A. A FE670. A FE6D0. -etc.

Occasionally you'll see a ' DUP ' entry. This occurs when 2 lines in the listing contain the same label (ie when there's a label on the macro and on the instruction.) Just skip it. I tried to fix it, but, give me a break, I'm 81. If you were to enter the same address twice, the 2nd would remove the 1st. This is a crummy fix for that.

Input is the SYSIN file. This is the SYSIN file I used to test QBR. It looks better with a fixed font.

Everything with a blank, or "*" in col-1 is a comment. To save a line in case you want to use it, just move it right a bit.

Note that I saved the .BAT file and the Z390 command. QBR assumes that you'll load your program in high memory.

If you do NOT do that, you need to tell it you load location LOADLOC=????? (no period)

* EITHER A BLANK OR AN "*" IN COL-1 IS ALWAYS A COMMENT. THESE ARE CONTROL CARDS I USED TESTING QBR.

COMPRESS=Y (squish spaces from ATFILE)

ATFILE=Y Write AT commands, or LIST commands for all instructions

CMDFILE=Y Write AT commands for labels listed in LABEL= lines.

LABEL= are the business end. NAME will just select that keyword. NAME* will select it and any suffixes.

COMMAND= just puts stuff in the file that I might want.

After you run the program, there are 2 output files, and also what's on the E390 screen. i use the E390 screen. I cut-n-paste it to a NOTEPAD file.

When I'm testing, I generally have 3-4 SPFlite screens open in addition to the NOTEPAD file, and the Z390 screen.

I look at the source, a output file(s) that the program I'm testing created, and the control card that the program uses.

When I'm working, I always put this at the end of a program I'm working on.

END QBR

What that does is to align my program on a 4k boundary so that locations, and offsets, match.

I only write batch programs these days, so they're not re-entrant. I always start my programs with:

TEST START 0

USING *,13

STM 14,12,12(13) I'VE GOTTEN INTO THE HABIT OF USING

ST 15,8(13) REG13 FOR BOTH BASE AND SAVE AREA.

ST 13,4(15) JUST MAKE SURE THAT THERE'S NOTHING

LA 13,0(15) THAT USES THE SAVE AREA BEFORE WE'RE

Note that I can't do anything needing the save-area for the first 72 bytes, but using 13 for both base and save-area gives me an extra register. I guard them jealously, using 14, 15, 0, and 1 as often as possible. In general, my base registers are high, and work registers are low. BUT the TRT instruction puts a byte in reg-2, so be careful. Also, I often overlay the first work with either X'4400D000' (causes a S0C3) or B INTERNAL-RESTART-ADDRESS so I can try again. It's easy to J 13r%

I ran the QBR program as I was testing QBR. There's extra stuff on the console during setup, and at the end, but the usable file contained AT and LIST commands from the LABEL= records, and then the stacked file at the end, with only AT commands. I make no attempt to get the length for the LIST command. I just use 96.

QBR 12/21/22 14.51 VER 01.03 (4 USE WITH Z390) -LIN LYONS

Then there's lots of stuff from the SYSIN file, and an indication that I'm setting it up correctly. And then the important stuff.

I HAVE DYXLEXIA, ATTENTION DEFICIT, AND OTHER HANDICAPS. HENCE QBR,

WHICH MAKES USING TSO TEST EASIER FOR ME ON Z390.

IF YOU SET UP THESE SYSIN AND BAT FILES, YOU'LL SEE HOW QBR WORKS.

WHAT I DO, WHEN I START TESTING, MAYBE FOR PROGRAM RACHAEL,

IS SET UP THE BAT AND SYSIN FILES TO READ THE RACHAEL.PRN FILE

THEN I HAVE A COUPLE SPFLITE (OR ???) WINDOWS OPEN WITH THE

RACHAEL SOURCE, AND THE ATFILE.

I USUALLY KEEP THE COMMAND FILE IN NOTEPAD, BECAUSE I FIND IT EASIER.

AND, OF COURSE, THE Z390 WINDOW, MADE FULL SCREEN HIGH.

SO I HAVE 3-4-5 WINDOWS OPEN. A LARGE MONITOR HELPS A LOT.
