mIRC does not have arrays. The nearest and best alternative to arrays in mIRC, is dynamicly named variables. For example, %var1, %var2, %var3, %var4 etc.
To set a dynamically named variable, you simply join two variables together, using square brackets, as follows:
set %var [ $+ [ %i ] ] MY VALUE
This code shows you how to emulate an array, using this method:
set %i 1
while (%1 <= 10) {
set %var [ $+ [ %i ] ] %stuff_variable
}
while (%1 <= 10) {
set %var [ $+ [ %i ] ] %stuff_variable
}



Square brackets are redundant there. Use “set %var $+ %i”
