Ok PICNIC
You bit quick, & think well, so here is the Feast, with restrictions.
THIS VERSION IS NOT READY FOR RELEASE, but you can play with what I have.
I made it so I could look into the little .COM files that came out when DOS 1 was being created to see how A REAL MAN writes assembly. You might find that kinda fun too.
RULE #1 DIS.COM will dis dis but don't. You will waste a lifetime writing in the labels, then next week I will release the source code and you will regret the hack.
BUTT, dis will dis dis and you will see lots of 29k .inc files that NC.exe will just barely edit.
RULE #2 make 3 copys of it DIS1 DIS2 DIS3 and edit them. You can set the defaults at the top by changing the FIRST LETTER of the line to a CAPITOL LETTER = ON & lower case = off.
Then any.com you DIS can be either a DECIMAL DUMP that always assembles to exactly the same as the original com, or AN.ASM that DUMPS OUT TEXT or NOT, and that is your three. With that you can use the output to FILL IN the output from other disassemblers that already have the labels.
To get ACTUAL LABELS instead of a decimal number, use the HEX DUMP on the right of the line.
IT IS IN BYTE FORM and the labels are Little ENDian so you have to reverse the last 2 HEX bytes with a L in front and you have your label. So in effect the label info is already written on the line
That is why it takes for ever to properly DIS a LARGE.ASM so up to a 2k.com is easy enough.
ANY WAY I'm looking forward to your FEED BACK, bitdog2u at gmail

PS, I run a 100% dos computer and code using DIRECT MEMORY read/writes to Video seg & BIOS seg.
I don't think my stuff will run in a DOS BOX. So if my stuff is total crap and won't run,
I would like to know what it doesn't run on, cuz it runs fine on mine. What is your CPU, YEAR, OS, ETC ?

CandyMan has a disassembler also....
