variable set

Post by NewzUK »

Hi - is there a way to set a variable just once when the bot starts up, but then does not get set again when there's a rehash?

Thanks in advance.

no, but there is an easy workaround:

Code: Select all

if {![info exists myvar]} {
   set myvar ""
}
Tip: this command can also be used to check if an array element exists.
