GOAL:
How to retrieve Operating System environment variables into Progress 4GL
GOAL:
How OS-GETENV works
FACT(s) (Environment):
Progress 8.x
Progress 9.x
OpenEdge 10.x
All Supported Operating Systems
FIX:
Progress added the functionality of a 4GL command to get a currently set environment variable interactively in Progres 8.x.
The 4GL command is OS-GETENV. When used in 4GL it will retrieve the specified variable directly from the operating system.
This is an example code on how to do this in Version 8:
Def var shell as char.
shell = os-getenv("TERM").
Display shell.
This will also get the value for the TERM variable for use in the 4GL code with much less coding.
