Hi,

if for example i have :

define PRINT(x) fprintf(stderr, x);

and in code i append it : PRINT(("print this")) output is : [print this]

if i append it : PRINT(("print %s", "this")) output is : [this]

could someone explain me why it receives just the "this" argument and not the whole string ?

I don't understand in which context an image block macro would be preferable to an image inline macro. I played around with a little test document and the only difference I could see is that I could "inline" (who would have guessed ;-)) the inline macro. So why not always use the inline version? >>> More
