SUMMARY
The presence of a CLEAR statement in the following event handling routine generates an "Illegal function call" error at compile time: CLEAR ,,800 KEY(2) ON     ON KEY(2) GOSUB 200 WHILE INKEY$="" : WEND PRINT "this is a test" END 200 CLEAR ,,800 PRINT "this worked" RETURN The error occurs because the CLEAR statement changes the stack. The CLEAR statement is not allowed in an event handler because it would destroy the return address.
