- * $CATEGORY$
- * DOS/BIOS
- * $ONELINER$
- * Determine the amount of conventional memory installed
- * $SYNTAX$
- * FT_SYSMEM() -> nMemSize
- * $ARGUMENTS$
- * None
- * $RETURNS$
- * A numeric corresponding to the number of K memory.
- * $DESCRIPTION$
- * FT_SYSMEM() simply reports the amount of conventional memory
- * (up to 640K) installed.
- *
- * FT_SYSMEM() uses DOS interrupt 12h to get this information.
- * For information, refer to Peter Norton's _Programmer's Guide
- * to the IBM PC_ (Brady).
- *
- * $EXAMPLES$
- * QOut( "Conventional memory installed: " + Str( FT_SYSMEM() ) + "K" )
