Hi BOB,

May I ask you your opinion about a MACRO SHEDULER script?

What do you think about the following script?

Let>k=0
Repeat>k
Add>k,1
Message>First loop%crLf%Pass %k%
Wait>1
Until>k,5

Message>End of first loop
Wait>2

Let>k=0
Repeat>k
Add>k,1
Message> Second loop%crlf% Pass %k%
Wait>2
Until>k,5

I’ am not so happy with the answer from support:

You've used the same loop counter variable for each loop so the second Until will loop back to the first Repeat. Use different loop counter variables.

The solution from support avoid loop back to the first loop and is so hiding a bug. That’s my opinion.

I would love to have your opinion "BUG or NO BUG"

Mr response:

Questions like this should be posted to the general forum so that we all can learn from the discussions. I will reply here, but will also post to general forum.

I think their response is consistent with my understanding of how their compiler works. You need to changd the second Repeat>k to some other variable like Repeat>n.

When the end of routine is completed, the compiler reads the script again, starting from the top. It will then pick up the first instance of Repeat>?.

The same thing happens with Label>, SRT>, Dialog>, etc.

In my opinion, I don't think it is a bug, it is just knowing how the system will respond to the script. Every language has its own differences, but once you understand them, you can work with them.
