Well, not so much in the above mentioned code, but what I read and know, specialy in clipper, full comparisons of macros versus code block/name substitution was there.

To support macros, it actually needs a kind of mini compiling engine to compile that code which is substituted be a macro, so as many times u run that same line of code, every time it will compile the same code, no matter you have done changes or not..

Whereas that is not the case with code blocks...

This all info. I got from a book of Mr. Rick Spence

Programmer's Guide to Clipper. There is a full detailed chapter on this thing and he has strongly recommended not to use macros.

Now being a xBase lang. I guess same thing applies to Fox Pro also.

Do you still think/suggest to use macros overall(not particularly in this case)
Pls advs.
