The /goto command allows you to jump to another part of the code. The goto command can only jump to a label within the same event, alias, or menu. The label must have been parsed by mIRC previously inside that event/alias/menu or the label is considered undefined. Calling a goto on an undefined label will result in a label not found error. Labels can be plain text strings or variables
Note: A goto cannot jump to a label that was skipped earlier in the code.
Synopsis

None
Parameters
None
Example
; /is_even <1-9> ; ; Example: /is_even 2 ; 2 is an even number. ; 2 is a prime number. alias is_even { goto $1 :0 | echo -a You typed zero. | return :4 | echo -a $1 is an even number. :1 | :9 | echo -a $1 is a perfect square. | return :2 | echo -a $1 is an even number. :3 | :5 | :7 | echo -a $1 is a prime number. | return :6 | :8 | echo -a $1 is an even number. | return :error echo -a Only single-digit numbers are allowed! reseterror }
Note that skipped labels cannot be jumped into.
; This example shows that a goto point not being parsed previously by mIRC cannot be reached. ; alias testing_goto { if (1) echo -a 1 elseif (1) { echo -a 2 | :test } goto test }
The script above will produce the following error:
* /goto: 'test' not found (line 3, scriptfile.mrc)
