set(3)

                                  set(1fmli)
     _________________________________________________________________

   set, unset -- set and unset local or global environment variables 

Synopsis

   set [-l variable[=value]] . . .
   set [-e variable[=value ] ] . . .
   set [-ffile variable[=value ] ] . . .
   
   unset -l variable . . .
   unset -ffile variable . . .

Description

   The set command sets variable in the environment, or adds
   variable=value to file. If variable is not equated it to a value, set
   expects the value to be on standard input. The unset command removes
   variable. Note that the FMLI predefined, read-only variables (such as
   ARG1), may not be set or unset.

   FMLI inherits the UNIX environment when invoked:
   -l
          sets or unsets the specified variable in the local environment.
          Variables set with -l will not be inherited by processes
          invoked from FMLI.
   -e
          sets the specified variable in the UNIX environment. Variables
          set with -e will be inherited by any processes started from
          FMLI. Note that these variables cannot be unset.
   -ffile
          sets or unsets the specified variable in the global
          environment. The argument file is the name, or pathname, of a
          file containing lines of the form variable=value. file will be
          created if it does not already exist. Note that no space
          intervenes between -f and file.

   Note that at least one of the above options must be used for each
   variable being set or unset. If you set a variable with the -ffilename
   option, you must thereafter include filename in references to that
   variable. For example, ${(file)VARIABLE}.

Examples

   Storing a selection made in a menu:
   name=Selection 2
   action=`set -l SELECTION=2`close

Notices

   Variables set to be available to the UNIX environment (those set using
   the -e option) can only be set for the current fmli process and the
   processes it calls.

   When using the -f option, unless file is unique to the process, other
   users of FMLI on the same machine will be able to expand these
   variables, depending on the read/write permissions on file.

   A variable set in one frame may be referenced or unset in any other
   frame. This includes local variables.

   When a variable is evaluated that does not specifically reference a
   file, the local environment and UNIX system environment are searched
   in that order. (When a set -l and a set -e is done for the same
   variable, the variable evaluates to the value used in the set -l
   command.)
