Reading Environment Variables

by Richard Russell, May 2011

You can read the environment variables associated with the current process using code similar to this:

        PRINT FNenvironment("PATH")
        PRINT FNenvironment("USERNAME")
        DEF FNenvironment(envar$)
        LOCAL buffer%, size%
        SYS "GetEnvironmentVariable", envar$, 0, 0 TO size%
        DIM buffer% LOCAL size%
        SYS "GetEnvironmentVariable", envar$, buffer%, size%+1
        = $$buffer%
