Previous Post: PC/370 Assembler Object Code Translator
With regard to my previous PC/370 Object Code Translator post the components are now available to test on your own Windows machine. Later versions of Windows require DOSBOX to execute (Information below).

TD021 Demonstration ZIP File: CLICK HERE
TD021 Demo - ZIP Contents:
TD021.COM - PC/370 Executable COM File
E370R42.EXE - PC/370 Runtime Execution Module
@TD021_demo.txt - Instructions
E370R42.EXE is the PC/370 Runtime Execution Module. It is part of the archived PC/370 R4.2 Package created by Donald Higgins. There are numerous sites where the package may be downloaded from (not required to run the demo).
Here's one of the Free Download sites: CLICK HERE

TD021 Function Keys:
KEY FUNCTION
======= ==============================
@K#ESC EXIT PROGRAM
@K#PGDN PGDN - Pg Down (16 lines)
@K#PGUP PGUP - Pg Up (16 lines)
@K#F1 F1 - Page Down (16 lines)
@K#F2 F2 - Page Up (16 lines)
@K#F3 F3 - Page Down ( 1 line )
@K#F4 F4 - Page Up ( 1 line )
@K#ARWD DOWN - Pg Down ( 1 line )
@K#ARWU UP - Pg Up ( 1 line )
@K#TAB TAB - Forward Half-Word
@K#TABL Shft-TAB - Back Half-Word
@K#ARWL LEFT - Back Half-Word
@K#F10 F10 - Step thru code (50)
@K#HOM HOME - Top of Module
@K#END END - End of Module
======= ==============================
OTHER KEYS will tab through each instruction (or a halfword if not a recognizable instruction).
DOSBOX can be downloaded for free at DOSBOX.COM
Running the Demo is very simple.
Unzip the demo files into a folder (I'm using C:\PC370X).
Install & Launch DOSBOX from your desktop
Perform the following line commands:
Z:\> MOUNT C C:\
Z:\> C:
C:\> CD PC370X
C:\> TD021
The process evaluates the opcode at the current offset pointer & displays the attributes along with the translated source code. If it is not a recognizable opcode it displays the hexadecimal values for a generic halfword. The pointer is recalculated based on the instruction length or the particular navigation key pressed.
NOTE - This is a simple translator based on the current pointer position - it is not a live "real-time" debugger tool. Using the TAB keys (TAB=Forward & Shift-TAB=Backward) the pointer is moved & evaluated in halfword increments - the resulting source code displayed is not an accurate representation of the actual module - it is indicative of the pointer position only.
Thanks for the positive feedback - hope someone finds this interesting & fun...
