A while ago dtech10 posted a script to make oneline.com, which I made and would have sworn it worked.

Now I'm getting the first char stripped.

Like this:

C:\temp\->oneline 123456
23456
C:\temp\->

I think I'm losing my marbles.

Here's the script:

###
N ONELINE.COM
A 100
MOV AH,2
MOV SI,82
MOV,DL,[SI]
CMP DL,D
JZ 113
MOV AH,2
INT 21
INC SI
JMP 105
MOV AH,4C
INT 21

R CX
17

If at first you don't succeed, you're about average.

Hi Mechanix

The Syntax is correct.
It works ok with my WinXP.
Do'es it produce the same from a batch file.
ie

oneline 123456 > File.txt
echo 789 >> File.txt

File.txt should now contain the line
123456789 on one line.
If ok maybe it's something to do with your
environment Prompt variable.

Hi d10,

My file.txt contains:

23456789

!!!

and my prompt is:

C:\temp\->echo %PROMPT%
$P$G

Any ideas?

TIA

Hi d10,

I single stepped through to the first INT 21. Now I'm really mystified.

Hi Mechanix
This might help.

MOV SI,82 Rem Address of Arguments.
rem Note at 81 should be the leading space.

Hi d10,

Yeah, that works. But I have NO idea why.

Notice that the original works in debug if I 'g 100'.

And this dump from the original shows the string does indeed start at offset 82.

C:\temp\->debug oneline.com 123456
-d 80
149E:0080 07 20 31 32 33 34 35 36-0D

I'm really smoked out on this one. I have a sinking feeling we're never gonna know.

If at first you don't succeed, you're about average.

Hi Mechanix
Beats me. Very confusing.

Hi d10,

I'm willing to just admit I can't figure it out.

But the nightmare scenario is I use offset 81, then some other day it decides to unclude the space.

SHEESH

I tried it in DOS and it worked as expected.

What really baffles me is why it works in debug and not at the prompt. [w2k]
