Get Environment Variable Function

Contributed by: Darin McBride

There are actually quite a number of ways to get OS/2 environment variables. Too often, however, I find myself using the value('myvar',,'OS2ENVIRONMENT') method. I don't find that readable. Take the following snippet, save it as 'getenv.cmd', and you have a convenient, and readable, method - much like us old C programmers are used to!


 


/*
 * GetEnv
 *
 * Parameters:
 *    OS/2 environment variable to look up.
 */
return value(arg(1),,'OS2ENVIRONMENT')
