echoes text in a specific color - help

Hi! I'm new at the forum.
First I'd like to thanks, 'cause I already used many tips and examples of codes posted here!
Now, my question:
- I'm trying to use the echo function posted here, in order to echoes with colors. It works fine, but I need to have a screen with many rows (scroll) and when I use the echo function, the screen buffer is missed. It seens like the cmd window resizes each time it calls the echo and then turn back to the original size and some upper rows are missed.
Does anybody know how to solve that?
Thanks a lot!

Well, I'm getting the famous for /f bug on XP, and did a dirty quick fix.
I see what u mean now, the screen buffer is being eaten and it seems to be caused by the COM file,
I know close to nothing about COM files, let's wait for an assembly wizard to pass by...
I'm interested in which OS you use, as you say it works perfectly with you, win7 ?
Code: Select all
@echo off &setlocal enableDelayedExpansion
for /l %%? in ( 1, 1, 50 ) do (
call :echo 0C. "Hello "
call :echo 0F "world"
)
pause
exit /b 0
:echo col txt -- echoes text in a specific color
:: -- col [in] - color code, append a DOT to omit line break, call 'color /?' for color codes
:: -- txt [in] - text output

I'm using Win7, but I'm experiencing the "buffer problem" even in win7 and XP.
The same problem occours using ColorMsg.com that u mentioned before.
It really seens something related with .com files.
Let's see if somebody else can help.
Thanks.

After more tests I've realized that it keeps only the 50 last lines.
I don't know why just 50...
