INTEGER Variables

An INTEGER variable is defined as a short int in C. You are passed a pointer to the data location. This example shows how to access an INTEGER from a C routine.

BASIC Program

10 INTEGER I

20 I=256

30 CALL Imp3( I )

40 PRINT I

50 END

60 SUB Imp3( INTEGER A )

70 A = A * 3

80 SUBEND

Prototype

1 END

10 SUB Imp3( INTEGER A )

20 SUBEND

C Program

#include "csub.h"

imp3( npar, a )

int npar; /* number of parameters */

intptr a; /* integer data pointer */

{

*a = *a * 3; /* return a new value */

return( 0 ); /* no errors */

}
