Re: set environment variable

Hi, thanks i do that, anyway the wole process is for set envirnment
variables before an user runs his 4gl menu of programs.

In other program that doenst have ui, i just DISPLAY several
MYVAR=123; export MYVAR
then i call it from a shell:

fglgo my4gl >> /tmp/mktempfile
source /tmp/mktempfile
rm /tmp/mktempfile

But now i need to show a options menu so DISPLAY to console cant help
me :)

thanks again!

You can't really do that..

You're testing for having set something in the environment from a process
thats been run and finished, and you cant set the environment in a parent
process from a child process.

You can't even do that from a shell script - the closest you can get is
to 'source' the settings so they are read into the current settings. If you
want to take this approach - you might be able to generate a 'settings' file
and then source that, eg :

$ fglgo my4gl
# my4gl generates my4gl.env

$ . my4gl.env
$ echo $MYVAR

You should be able to set the environment variables for use within the 4gl
program by calling the C function putenv or setenv (depending on your
platform) - but that will only set it for programs run from the 4gl program
(eg via a RUN command).
Of course - Aubit4GL has a "aclfgl_setenv" to make this easier ;-)

Hi, i note there is not a FGL_SETENV function in traditional Informix
4GL

Anybody has resolved how to set an environment variable (linux, bash)
from 4gl program??

i need:

$ fglgo my4gl

   -- my4gl must set MYVAR=SOMEVALUE

$ echo $MYVAR
SOMEVALUE

Can make this works....

Thanks!
