Thank you: I´ve learned something new again....


 > uchar * A="Hello";
 > uchar A[]="Hello";?

Sorry, I´ve missed the astrisk. The second is equivalent. To be sure I´d
   put on my good ol´ Turbo C:

#include <stdio.h>
#include <conio.h>

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

int main (void)
{
	char *A   = "Aello";
	char B [] = "Bello";
	char C[255];
	char *D;

/*
C = "Cello";  ERROR: LValue required, but: */
	strcpy (C, "Cello");
	D = "Dello";

	printf ("%s\n", A);
	printf ("%s\n", B);
	printf ("%s\n", C);
	printf ("%s\n", D);

	return (0);
}


Best regards

Harald
