If you need to run multiple commands against one of the computers in the list, you can structure in the following way (my comments formatted for batch files; change double percents (%%) to single (%) to run on command line:
FOR /f %%a in ('complist.txt') do call :MY_SUB %%a GOTO SUB_DONE :MY_SUB
REM Here, the computer name was passed as a parameter, so it comes in as %1
REM Example - copy a file to the computer copy myfile.txt \%1c$
REM run this to end the subroutine
GOTO :EOF :SUB_DONE
REM subroutine is finished, rest of the batch file continues
