Its not directly a wish, currently. Just a thought.
New built-in variables A_Break and A_Continue, updated on every continue or break command. They could hold the argument given from that command.
The default, if no argument was specified, the value of last A_Index (that was also requested) could be used.
Example:
| Code: | Loop
{
if a_index = 10
break
}
msgbox %a_break% ; shows "10"
Loop
{
if a_index = 10
break 2 * 4
}
msgbox %a_break% ; shows "8" |
But I am not sure what to do, if the Loop is nested and if they should resetted on every new loop or whatever.
edit: ups corrected a small error in code above. |

is the reason to try and tell whether it continued or broke last? if they are two variables, you have no way of knowing which one was more recent. I think it's good to come up with ideas like this. What can you see it being used for?

Loops are often used to count things such as the number of files in a folder so a variable like A_Break (or A_LastIndex which I prefer) would be helpful.

This could us help to determine why and if a Loop command is exit. I dont think, that it is essential, but it would be used quite frequently often. The last A_Index (A_LastIndex) count is just one often asked or needed example.
What would you await A_Break should hold, if Loop exits without a break? I am also not sure how to tell, if a new iteration started from a continue or not. |
