Basic for loop behaving strangely

[philranger]

Hello!

MMM pro 8.2.0.0


1 | FOR | I | = | 1 TO 5 | NEXT

2 | RUN ACTION | MESSAGE PROMPT | %I%

3 | FOR | NEXT

1st message is "2", not "1" as expected.  Anyone else has the same?

Thanks!

Hi philranger

Are you trying to count from 1 to 5?
If so start at 0. The first iteration increments the FOR loop %I% counter.

1 | FOR | I | = | 0 TO 5 | NEXT
2 | RUN ACTION | MESSAGE PROMPT | %I%
3 | FOR | NEXT

Thanks!  Can you put a for loop inside a for loop, the code below doesn't work...


1 | FOR | I | = | 1 TO 5 | NEXT
2 | FOR | J | = | 10 TO 13 | NEXT
3 | RUN ACTION | MESSAGE PROMPT | I=%I%,J=%J%
4 | FOR | NEXT J
5 | FOR | NEXT I

Hi Phil,

Yes you can. Basic FOR LOOPS can be nested but they don't work as your have them in your example.
They work more like this:

1 | FOR | I | = | 0 TO 3 | NEXT
  2 | RUN ACTION | DEFINE STRING VARIABLE | %parent%::%I%
  3 | FOR | I | = | 0 TO 5 | NEXT
     4 | RUN ACTION | DEFINE STRING VARIABLE | %child%::%I%
     5 | RUN ACTION | MESSAGE PROMPT | Parent=%PARENT%of5 Child=%CHILD%::loop status::1
  6 | FOR | NEXT
7 | FOR | NEXT

Thanks Steve, I wouldn't have guessed that alone!
