Sorry to be so rude but... some things buts must told...
ScatMan did you ever lost time to read me mirc.hlp or you are just trying to be the biggest Post maker in here??
If you did it, you would understand that some of the script commands are exe in the client "mirc" an when it doesn't recognize some it sends them to de server.
In your case why tha **** you need to make /if?
Why to you insist to look for bugs in mirc so desperately? Everybody knows your the biggest bug reporter here, to bad 98% of those bugs aren't bugs and the other 2% where already reported. Learn to script than while you are programming, if you find any problem, first try to resolve it using your head and mirc's documentation, then if you can't report the supposed problem.
If you are trying to exec some command in command line don’t forget to make duple //
And yes /if works for everyone, except you, try this
//if (scatman isin boring scatman) echo scatman is boring
your splay bug its another of those "bugs" that can be avoided.
Thanks
