(English: "number of time
s the macro...")
Code: Select all
Macro fry
Debug MacroExpandedCount
EndMacro
; this will always be 1
For z = 1 To 10
fry
Next
; this will count 2,3,4

Doesn't matter loop style (for/while/repeat), so does this loop format
Code: Select all
Macro fry
Debug MacroExpandedCount
EndMacro
x = 0
more:
fry
x+1
If x < 10 : Goto more : EndIf

MacroExpandedCounts returns the number of times the macro is replaced in the source. This has nothing to do with how much the piece of code is executed.

That's correct, because macro expansion happens at compile time, while the for/next loop is executed at runtime.

In this case, the documentation needs to be changed.

How would you change it? It already seems to be clear with this preface in the section on macros:
Macros are a very powerful feature, mainly useful for advanced programmers. A macro is a placeholder for some code (one keyword, one line or even many lines), which will be directly inserted in the source code at the place where a macro is used.
Source code only exists at compile time.
