**CIGAL Reference Manual, Chapter 4 (Variables): path**
===== Path -- String variable of directories to search for macros and menus =====
**usage: path = string**

PATH, a character string variable, defines internally which disk directories
to search through when looking for CIGAL macro files or menu files.  PATH is
homologous to the UNIX or DOS PATH environment variables. Individual directory
pathnames are separated by the '|' character.  The current directory is
indicated by a null entry.

For example, if the PATH string is:
          path = '|c:\\imp\\|c:\\cigalsys\\'
then naming a macro or menu will cause CIGAL to search 3 directories.
Therefore a command like:
          menu testmenu
searches, in order, for a file named:
          testmenu.mnu                    (in the current directory)
          c:\imp\testmenu.mnu
          c:\cigalsys\testmenu.mnu

The first of these that is found will be used.  (The .MNU suffix is added)

NOTE: Each directory name in PATH includes the final '\' character.  This lets
CIGAL simply append filenames to directory names to find files.  Also, remember
that to get a '\' character into an CIGAL string you must enter it as '\\'
because the backslash is used as a special character in strings, as in the
C language (see 
[[jvs:cigal:manual:chapter1:strings|STRINGS(1)]]).
