PPWIZARD is a free preprocessor for HTML, REXX, Visual Basic or any text files.

GetEnv()

This is a rexx function provided by PPWIZARD. This routine (like all PPWIZARD extensions) can be used with any operating system supported by PPWIZARD.

This function returns the value of an operating system environment variable. An empty string is returned if the variable is unknown.

The parameters are as follows:

1. Variable Name
   This is the name of the environment variable.

2. Die if Missing?
   This optional variable is used to tell ppwizard to abort if the variable could not be found. To tell PPWIZARD to abort pass upper case 'Y'.

Example

    ;--- Lets keep all WORK/HOME conditional logic here -------------------------
    #define AtHome  translate(GetEnv("PRJSRCDIR", 'Y')) =  "E:\DB\PROJECTS\HOMEPAGE\HTML"
    #define AtWork  translate(GetEnv("PRJSRCDIR", 'Y')) <> "E:\DB\PROJECTS\HOMEPAGE\HTML"
    
    ...
    ...
    
    ;--- External Links ---------------------------------------------------------
    #if    <$AtHome>
            #define ExtLink   <A TARGET=_top HREF="{$URL}">{$VISIBLE=`{$URL}`}</A>
    #elseif
            #define ExtLink   {$VISIBLE=`{$URL}`}{$URL-}
    #endif
