The /while command is a construct in the mIRC scripting language that can perform repetitive operations. The block of statement inside the while loop will get executed as long as the condition is true. You can manually break out of a loop by using the Cltr+Break key combinations.

How to iterate over lines of a file
;Read all lines of a file: var %file file.txt var %i 1 | while (%i <= $lines(%file)) { echo -a line %i - $read(%file,nt,%i) inc %i } ;Read from line 5 and stop at line 10: var %file file.txt var %i 5 | while (%i <= $lines(%file)) { echo -a line %i - $read(%file,nt,%i) if (%i == 10) break inc %i } ;Note: These are the code snippets that you should use inside your alias or script.
Other examples of using a loop
Example 1:
;Example 1 Alias CountToTen { ;Create a counter variable, set it to one var %Counter = 1 ;Loop while the counter variable is less than or equal to ten. while (%Counter <= 10) { ;Print out the value of the counter variable echo -a Count Number: %Counter ;Increase the counter variable by 1 inc %Counter } }
The above example will output:
Count Number: 1 Count Number: 2 Count Number: 3 Count Number: 4 Count Number: 5 Count Number: 6 Count Number: 7 Count Number: 8 Count Number: 9 Count Number: 10
Example 2:
;Example 2 Alias ListVars { ;Check if there are any variables set if (!$var(*,0)) { echo -a There Are No Variables. halt } ;Set a counter variable var %a 1 ;Loop while the counter variable is less than or equal to the total number of variables while (%a <= $var(*,0)) { ;Print out the variable and its value echo -a $v1 $+ ) $var(*,$v1) = $var(*,$v1).value ;Increase the variable by one inc %a } }
The above example will output something like this:
1) %Foo = FooBar 2) %Bar = BarFoo
