leap.txt : hop.asm skip.c jump.pli ! print $** lpt1:
The example above executes the following three commands, regardless of the modification dates of the dependent file:
print hop.asm lpt1:
print skip.c lpt1:
print jump.pli lpt1:
leap.txt : hop.asm skip.c jump.pli
! print $? lpt1:
The example above executes the print command only for those dependent files with modification dates later than that of the leap.txt file. If hop.asm and jump.pli have modification dates later than leap.txt, the following two commands are executed:
print hop.asm lpt1: print jump.pli lpt1:
