Chapter 4-7: Predefined Fields

RETURN CODE


This field is returned whenever a CALL or RUN statement is completed. Its value is determined by the process that was called or run.


         RUN          /appx/deal               END? N FAIL 0
         IF           --- RETURN CODE                EQ 52
   T     GOSUB      :ACE OF SPADES
 
 

Assuming that the directory /appx contains the following sample C program, this program will be executed and a return code of 1 to 52 will be passed back to the APPX process that executed the RUN statement.

/* deal.c */

#include <stdlib.h>

#include <time.h>

int main( int argc, char ** argv )

{

/*

** Initialize the random number generator

*/

   srand(( unsigned ) time(0) );

/*

** Return a random number between 1 and 52

*/

   return( rand() % 52 + 1 );

}
