I'm trying to get some legacy fortran code compiled on an SGI workstation. In the Makefile, the lines
.f:
co $@
do appear. Make exits with the error
sh: co: not found
I tried googling for that program, but to no avail. Does anyone know what this could be, and where to obtain it - given the short name, I hope that it is some kind of standard tool, rather than something specific to this very Makefile.
