Hi Tim,
I’ve been bitten by this a while ago. There is a difference in behavior
interpreted and compiled. Eg following piece of code:
1 C_OBJECT($obj)
2 C_TEXT($text)
3 C_LONGINT($long)
4
5 OB SET($obj;"property";"value”)
6
7 $text:=OB Get($obj;"nonexistent")
8 $text:=OB Get($obj;"nonexistent";Is text)
9
10 $long:=OB Get($obj;"nonexistent")
11 $long:=OB Get($obj;"nonexistent";Is longint)
12
13 ON ERR CALL("Errorhandler")
14 $long:=OB Get($obj;"nonexistent")
15 $long:=OB Get($obj;"nonexistent";Is longint)
16 ON ERR CALL(“”)
Interpreted: no error on lines 7 and 8, error on line 10 (54 - Argument types
are incompatible)
no error on line 14, but the error handler method wil be executed
Compiled: no error on lines 7 and 8, error on line 10 (-20007 Attempting to
retype by using a pointer)
On line 14, the error handler is not executed, but 4D displays error -20007
(Attempting to retype by using a pointer)
I would advice to always use the typing parameter (or test using OB is defined)
