and link. However, it does not work yet and thus still needs work. The *.asm files have had the following common changes: - 'keep' lines were eliminated - the 'mcopy' now takes the macro from the /obj/gno/bin/gsh directory. This is in anticipation of having the macro files generated from a single source file; there is a large amount of duplication. For the moment, the makefile merely copies the old macro files from the "M" directory to the /obj/gno/bin/gsh directory. - start each file with a dummy routine so that the source code winds up in the *.o rather than the *.root file. - added the 'setcom 60' directive; there were many source lines that were otherwise getting truncated. The makefile is a complete rewrite.
