Hello,
There is no hard coded limit for loop nesting.
And there is no limit on size of string.

Subject: [amibroker] Any limit of number
of nested loops ?
Tomasz,
Both 'for' and 'if' multi-stament worked in 'Guru' !
In theory, is there any limit on the number of nested
loops one may have for 'for' in AFL ?
Regards,
