-ipath "dirname[:dirname][...]"
The source program contains:
%INCLUDE partlist;
In a UNIX environment, the Compiler invocation is:
mfplx source_file -ipath ".;/u/libr1:/u/libr2"
In this case, the Compiler searches first for "PARTLIST" in the current working directory, then /u/ libr1, and finally /u/ libr2. If that fails, it searches for "partlist" (lowercase) in the same directories.
