Re: DOS Type into a variable

[Michael Ryan <michaelrtr@xxxxxxxxx>]

commandfileb.cmd wants the contents of filea.txt as a parameter, like to use
it as %1 in commandfileb.cmd. I thought I tried the commandfileb.cmd <
filea.txt technique and it didn't work...I was using the echo command in
commandfileb.cmd just to see the contents...I wonder if that makes a
difference.
