TurboC graphic Symbols

[RAMontante]

The simple graphics symbols you're referring to are just the way the CGA
graphics adapter displays the "nonprinting" ASCII characters --- that
is, values less than 32 or greater than 127 (decimal).  (The graphics
symbols assume that you aren't using any ANSI driver.)

You can see what your system will do by writing a simple program that
just displays each value:

#include <stdio.h>
int main(void)
{
	int i;
	for (i = 0; i <= 255; i++)
		printf("value %3d >>%c<<\n", i, i);
	return 0;
}
