OS-GETENV function

OS-GETENV function

Returns a string that contains the value of the desired environment variable in the environment in which the ABL session is running.

Syntax
OS-GETENV ( environment-variable ) 
environment-variable

The name of the environment variable whose value you want to find.

Example

This procedure prompts a user for a report name. It then builds the full pathname where the report will be stored, using OS-GETENV to find the DLC directory. Finally, the procedure displays the full pathname.
r-os-env.p
DEFINE VARIABLE pathname    AS CHARACTER NO-UNDO FORMAT "x(32)" 
  LABEL "The report will be stored in ". 
DEFINE VARIABLE report_name AS CHARACTER NO-UNDO FORMAT "x(32)" 
  LABEL "Please enter report name." . 
UPDATE report_name. 
pathname = OS-GETENV("DLC") + "/" + report_name. 
DISPLAY pathname WITH FRAME b SIDE-LABELS. 
Notes

If the environment variable is not defined, this statement returns the Unknown value (?).

This function returns the value of an environment variable defined before the ABL session started, not a variable defined during the session.

Since environment variables are case sensitive in some environments, make sure that the name you supply is the correct case.
