Could I please get some feedback from the group. I see from the other reply to my query, that this type of thing is not used much...but I suppose the experience does give one some new insights into the workings of the language...although not strictly speaking Obj-c I suppose.
I have changed the printf function to NSLog to comply with the authors wish to only use functions already presented in the book. ( I think printf is a holdout from the 1st edition.
sample output:
It feels kind of sloppy to me, and does not exactly comply with the code asked for, but it does seem to work. Anyway, that closes out that chapter!! Yeh

Code:
#import <Foundation/Foundation.h>
#define PRINTINT(var) NSLog(@ "x%i = %i", var, var)
#define PRINTX(n) PRINTINT( x ## n)
#define NAMEVAR(n) int x ## n
#define INITIALIZEVAR(n) NAMEVAR(n) = n
int main (int argc, const char * argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
int i;
for ( i = 1; i <= 100; i++){
INITIALIZEVAR(i);
PRINTX(i);
}
[pool drain];
return 0;
