SUMMARY
The example below demonstrates how to pass a fixed-length string from compiled Basic to Microsoft C by far reference.

This information about inter-language calling applies to QuickBasic Versions 4.00, 4.00b, and 4.50 for MS-DOS and to Microsoft Basic Compiler Versions 6.00 and 6.00b for MS-DOS and MS OS/2.

Code Example
REM Basic Program

DECLARE SUB StringFar CDECL (_           BYVAL p1o AS INTEGER,_            BYVAL p1s AS INTEGER,_            SEG p3 AS INTEGER) CLS DIM a AS STRING * 15 a = &quot;This is a test&quot; + CHR$(0) CALL StringFar(VARPTR(a), VARSEG(a), LEN(a)) END

/* C Routine */

void StringFar(a,len) char far *a; int *len; {   int i;    printf(&quot;The string is : %s \n\n&quot;,array); printf(&quot; Index      Value       Character\n&quot;); for (i=0;i < *len; i++) {        printf(&quot;  %2d          %3d            %c\n&quot;,i,a[i],a[i]); }; }
 * 1) include 

Output
The string is : This is a test Index      Value       Character 0          84            T   1          104            h   2          105            i   3          115            s   4           32 5         105            i   6          115            s   7           32 8          97            a   9           32 10         116            t  11          101            e  12          115            s  13          116            t  14            0
