This is really easy to write in C, just declare a static array of 256
unsigned chars and initialize it with the numeric values of the ASCII
characters.  Make sure the array position corresponds to the EBCDIC value
as you will use the EBCDIC value as the indice into the array, like so:

/* etoa.c */

#include <stdio.h>

typedef unsigned char byte;

static byte ascii[256] = {
	initializers, 
	go,
	here,
};

main()
{
	int c;

	while ((c = getchar()) != EOF) 
		putchar(ascii[c]);
}

I can mail you both the ASCII and EBCDIC array declarations
if you need them.
