I have been trying out throw and catch I did at first not know the definition of the different catches
Found a good one at last The B0 block is executed and: • catch. catches an error in B0 , whatever the setting of the debug flag 13!:0 <http://www.jsoftware.com/help/dictionary/dx013.htm> • catchd. catches an error in B0 , but only if the debug flag is 0 • catcht. catches a throw.<http://www.jsoftware.com/help/dictionary/cthrow.htm> in an explicit definition invoked in B0 2007/4/12, Henry Rich <[EMAIL PROTECTED]>:
As I understand the system my text is correct. throw. goes only to catcht., and catch. picks up other errors. If I'm wrong I hope someone will set me right.
