I can't get the array to work...I have everything else worked out. If someone wants to look at my code and help, I would appretiate it.

Code:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

const char a[][] = { /* morse.c:5: error: array type has incomplete element type */
	'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M',
	'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X',
	'Y', 'Z',
	'1', '2', '3', '4', '5', '6', '7', '8', '9', '0',
	' ', 
	".- ", "-.. ", "-.- ", "-.. ", ". ", "..-. ", "--. ", "....",
	"..", ".--- ", "-.- ", ".-.. ", "-- ", "-. ", "--- ", ".--. ",
	"--.- ", ".-. ", "... ", "- ", "..- ", "...- ", "...- ",
	".-- ", "-..- ", "-.-- ", "--.. ",
	".---- ", "..--- ", "...-- ", "....- ", "..... ", "-.... ",
	"--... ", "---.. ", "----. ", "----- ",
	"   "
};

void convert(char [], int);
int set_ary_num(int, int);
void help(char []);

main(int argc, char *argv[]) {
	if (argc < 3 || strstr(argv[1], "-h") != NULL) {
		help(argv[0]);
		exit(1);
	}
	if (strstr(argv[1], "-e") != NULL) {
		convert(argv[2], 0);
	} else if (strstr(argv[1], "-m") != NULL) {
		convert(argv[2], 1);
	} else {
		fprintf(stderr, "unkown option: %s\n\n", argv[1]);
		help(argv[0]);
		exit(1);
	}
	
}
void convert(char s[], int mode) {
	int i = 0, j;

	while (s[i] != '\0') {
		j = 0;
		while (s[i] != a[j]) {
			j++;
		}
		j = set_ary_num(j, mode);
		printf("%s", a[j+=35]);
		i++;
	}
}
int set_ary_num(int n, int mode) {
	return (mode == 0) ? (n += 35) : (n -= 35);
}
void help(char prog[]) {
	fprintf(stderr, "usage: %s [options] [string]\n"
		"options:\n\t-e\tenglish to morse\n"
		"\t-m\tmorse to english\n\t-h\tprint this\n",
		prog);
}

I've tried a few things for that, and I can't get anything to work...

phvia

PHVIA(3)						MBK PHYSICAL STRUCTURE DEFINITIONS						  PHVIA(3)

NAME

       phvia - mbk physical contact

DESCRIPTION

       The phvia structure is used to describe a via or contact belonging to a symbolic layout model, see phfig(3) for details.

       The declarations needed to work on phvia are available in the header file "/labo/include/mph402.h", where '402' is the actual mbk version.

       The following C structure supports the description of the via :
	      typedef struct phvia {
		 struct phvia	  *NEXT;
		 char		  TYPE;
		 long		  XVIA,YVIA;
		 struct ptype	  *USER;
	      } phvia_list;

       NEXT		   Pointer to the next phvia in the list.

       XVIA, YVIA	   Coordinates of the center of the via. Vias are macro generated patterns, so only their center is a matter of concern.

       TYPE		   Via type. The legal types for via are

			   CONT_POLY	       poly alu1  contact

			   CONT_VIA	       alu2 alu1  contact

			   CONT_DIF_N	       alu1 difn  contact

			   CONT_DIF_P	       alu1 difp  contact

			   CONT_BODY_N	       alu1 nwell contact

			   CONT_BODY_P	       alu1 pwell contact

			   CONT_VIA2	       alu2 alu3  contact

			   C_X_N	       L shaped N transistor corner filling

			   C_X_P	       L shaped P transistor corner filling

       USER		   Pointer  to a ptype list, see ptype(3) for details, that is a general purpose pointer used to share informations on the
			   via.
