To see whats going on, do this.. on mouseUp -- Local undeclared un-initialized variables evaluate as string values. myvar is "myvar" -- so the value returned is the name of the variable Meaning the engine doesn't see it as a variable -- and sees it as a string. answer myVar
put 1 into myArray[1] put 1 into myArray[2] -- 2 hitter here. Initialized with values, and the brackets force the engine to see this as an array variable. -- Functions as you would expect -- there is no value in element 3, but the engine sees it as a variable so it will answer empty answer myArray[3] -- this one, again has the brackets forcing the engine to recognize it as an array variable so it will answer empty. answer myArray1[3] end mouseUp On Sun, May 1, 2016 at 7:15 AM, <j...@souslelogo.com> wrote: > Hello again, > > Please take a long at the following script : > > on mouseUp > if myVar is empty then > answer 1 > else > answer 0 > end if > > put 1 into myArray[1] > put 1 into myArray[2] > > if myArray[3] is empty then > answer 1 > else > answer 0 > end if > > if myArray1[3] is empty then > answer 1 > else > answer 0 > end if > end mouseUp > > Is there any logic explanation why it answers "0" for myVar > and "1" for myArray and myArray1 ? > > Thanks > jbv > > > _______________________________________________ > use-livecode mailing list > use-livecode@lists.runrev.com > Please visit this url to subscribe, unsubscribe and manage your > subscription preferences: > http://lists.runrev.com/mailman/listinfo/use-livecode > _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
