does anubody know hot to be sure that system var are evaluated, i mean not changed. for example i cast spell target self and if enought mana - cast again, so in normal case it says not enough mana (with lpc 1000). actually i m sure that i dont have mana that time but if #mana > condition passes. what to do? i v found this:
set %eouxdelay #systime
while #systime = %eouxdelay
sleep 1
usefull, but still it doesn't always work
