When writing a mixed-language program utilizing modules written in
either Microsoft QuickBASIC or Microsoft BASIC Compiler, BASIC must be
the start-up controlling language. This step is necessary to activate
the BASIC language run-time support code.

For example, if a mixed-language program uses both C and QuickBASIC
modules, then QuickBASIC must be the controlling language. Thus, C
cannot call QuickBASIC without QuickBASIC first calling C.

This information applies to Microsoft QuickBASIC Versions 4.00, 4.00b,
and 4.50 for MS-DOS, to Microsoft BASIC Compiler Versions 6.00 and
6.00b for MS-DOS and MS OS/2, and to Microsoft BASIC PDS Version 7.00
for MS-DOS and MS OS/2.
