74 | =item fixpath |
75 | |
76 | Catchall routine to clean up problem MM[SK]/Make macros. Expands macros |
77 | in any directory specification, in order to avoid juxtaposing two |
78 | VMS-syntax directories when MM[SK] is run. Also expands expressions which |
79 | are all macro, so that we can tell how long the expansion is, and avoid |
80 | overrunning DCL's command buffer when MM[KS] is running. |
81 | |
82 | If optional second argument has a TRUE value, then the return string is |
83 | a VMS-syntax directory specification, if it is FALSE, the return string |
84 | is a VMS-syntax file specification, and if it is not specified, fixpath() |
85 | checks to see whether it matches the name of a directory in the current |
86 | default directory, and returns a directory or file specification accordingly. |
