While loops

I have been designing a new macro, using classical While loop structures, and was receiving errors.

So I looked again, at the manual....

Is it really true? no while command in mq2?

Sure, I can do similar structures with goto, but that has always been considered amatuerish coding since the early 80's.

Yes, no while command, but there is for/next

hmm, seems to me there are somethings one can do with while loops better than for loops, though perhaps I just need more experiance with for loops, ok, I will see if I can adjust to for loops

I agree, which is why LavishScript implements while/endwhile and not for. That's for ISXEQ though not MQ2

Beware that /for loops in MQ2 ALWAYS execute at least once so you can not use them to substitute directly for a WHILE loop.

Code: Select all

/for I 1 to 0
   . . . this code gets executed once with I = 1 . . .
/next I

You can use /goto loops. Something like this:

Code: Select all

   :loop
   /if (Whatever) { 
      /goto :endloop
   }
   . . . some code . . .
   /goto :loop
   :endloop

If you wanted the flexibility to NOT execute the loop at least once, wouldn't it be better to do:

Code: Select all

/if (whatever) {
   /for
   /do stuff
   /next
}

That's essentially how I got around it notad
