I'm not familiar with the details of CMD's scripting, but the thing I'd 
worry about is that if it drops blank lines, it might make other 
undesirable changes as well.  If I was using CMD, I'd probably look for 
a program like "sed" that was designed for editing.  sed itself is 
available for Windows; the command to echo all but the first line of 
input would be

   sed -e 1d < bowls-rr.ta68

or if I wanted to delete all the lines (if any) with % at the start,

   sed -e /^%/d < bowls-rr.ta68

This could be included in a larger .cmd script that went on to run the 
compiler.
