set environment variable

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 $MYVARSOMEVALUE Can make this works.... Thanks!

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 ;-) HTH On Friday 21 November 2008 14:01:34 eferreyra wrote: > 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! > _______________________________________________ > Informix-list mailing list > Informix-list@iiug.org > http://www.iiug.org/mailman/listinfo/informix-list -- Mike Aubury http://www.aubit.com/ Aubit Computing Ltd is registered in England and Wales, Number: 3112827 Registered Address : Clayton House,59 Piccadilly,Manchester,M1 2AQ

Sounds like a job for a 'report' then ;-) On Friday 21 November 2008 14:43:06 eferreyra wrote: > 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! > -- Mike Aubury http://www.aubit.com/ Aubit Computing Ltd is registered in England and Wales, Number: 3112827 Registered Address : Clayton House,59 Piccadilly,Manchester,M1 2AQ
