This allows you to recursively evaluate identifiers and variables in a line of text. read the helpfile (/help $eval or F1) sample: /set %network $network //echo -a %network this gives "$network" //echo -a $eval(%network,2) this gives "YOUR_$NETWORKNAME_HERE" //echo -a $eval(%network,0) this gives "%network" //echo -a $eval(%network,1) this is default and gives "$network" If it ain't broken, don't fix it!
