Compiler Symbol Definitions

Scroll Prev Top Next More

The following command line switch supports passing symbol definitions into the compiler. Syntax:

/C:symbol {=value}

Example

COMPIL MYPROG/RC/C:APPVER=2/C:GUI="VISTA"

This specifies the /RC switch, plus two instances of /C to define two symbols, APPVER=2 and GUI="VISTA". These definitions are treated exactly as if the following had been inserted at the top of the MYPROG source code:

define APPVER=2

define GUI="VISTA"

 

Note the need for quotes when defining a string symbol (per the normal rules of the DEFINE statement).

If the =value clause not specified, it is treated as = 0, i.e. the symbol is defined (responds to ++IFDEF <symbol> but it has a null value.
