Ok, I tried this, and got a few more errors.  Now my program looks
like this, both modules compile just fine -- but when the linker gets
to them it gives me an error:  

creating multiple.exe:
Error:  getsafe.o:  In function 'getsafe':
getsafe.c(8):  Error multiple definition of 'getsafe'
0:getsafe.c(8):  Error first defined here.

Sorry for the waste of bandwidth, but here are my proggies again.  I
am this | | close!!
/*getsafe.h */
char *getsafe(char *buffer, int count);

/*getsafe.c */
#include <stdio.h>
#include <string.h>

extern char result;
extern int result_num;

char *getsafe(char *buffer, int count)
{
 char *result = buffer, *np;
 if ((buffer==NULL) || (count <1))
   result = NULL;
 else if (count == 1)
   *result = '\0';
 else if ((result = fgets(buffer, count, stdin)) != NULL)
   if ((np = strchr(buffer, '\n')))
	 *np = '\0';
 return result;
}


/*main.c */
#include <string.h>
#include <stdlib.h>
#include "getsafe.h"

char result[80];
int result_num=sizeof(result);

int main(void)
{
  printf("Enter up to %d characters:  ",result_num-1);
 getsafe(result, result_num);
 printf("your string is %s",result);
 return 0;
}

Thanks again!
Stuart
