Only one thing to add to Patrick's letter :
This is all true and 
char x[1] is a char array with length 1.
There is formally no such issue like string in C, simply 
C-programmers are used to zero-terminated strings.
The world of C/400 is a bit different, as when you play with data 
base files (PF-s) alfanumeric fields are not "C-strings" - 
zero-terminated, but rather char arrays.
Funny is that when you use 
#pragma mapinc to make compiler automatically generate structures for 
records of PF-s you are going to use and record contain a CHAR field 
(1 byte), structure generates a definition of char ZZZ[1] - not a 
char, but char array of 1 element.
So you cannot compare like
if (ZZZ == 'N')
you must write 
if (ZZZ[0] == 'N')
