Here's a revised script: <hansl> open denmark function scalar heyhey (list in) catch var 20 in # 20 is too much -> error if $error return 1 else return 0 endif end function if 5 < 10 list lulu = LRM LRY IBO IDE scalar err = heyhey(lulu) if err print "function heyhey produced an error" else print "function heyhey went OK" endif endif </hansl> Allin

The point is that catch must always be applied directly to the gretl command (or built-in function) that might generate an error. In your example, the "var" command inside the function generates an (uncaught) error. In response to that error gretl aborts execution of the function and gets ready to abort execution of the script. And that involves tearing down any "if" conditionality that's currently in force (otherwise it will mess up subsequent script execution). However, when control returns to "main" gretl finds that catch is in place so it soldiers on, and encounters "endif", which is now "unmatched" since the preceding "if" has been erased. So this sort of thing is not going to work; you can't do a "delayed" catch, or in other words the catch must be moved inside the function. Allin
