=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. |
