how to feed keystrokes to a dos program?

[pcdos2k]

i need to feed "enter, y, y, y, y, y, enter" into fastvid.exe.
fastvid is a vesa optimizer but using its commandline options does
not use the entire video card memory even if explicitly indicated.

i would prefer an alternative solution that does not use any tsr or
tempfiles. my current batfile:

::::: vidfast.bat :::::
echo. > fastvid.yyy
echo y >> fastvid.yyy
echo y >> fastvid.yyy
echo y >> fastvid.yyy
echo y >> fastvid.yyy
echo y >> fastvid.yyy
echo. >> fastvid.yyy
fastvid.exe < fastvid.yyy >> nul
del fastvid.yyy >> nul
::::: end :::::

this is for a bootcd that assumes no writeable dos partition.

thanks.

A keystuffer TSR is probably the best way.

Do you just mean that you can't run the echo y >> fastvid.yyy
statement from the CD because it can't save to disk?

Could you just burn the final fastvid.yyy file to the CD?
I don't think the line
fastvid.exe < fastvid.yyy >> nul
would need to write anything to disk.

Or does this boot CD create a ram disk?  That is writable.

" >> nul" will suppress any messages.

i ended up writing the tempfile to %temp%, which is a ramdisk. thanks for the reminder.
