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.
