I thought that I already had a Set_Exists("Set_Name") : Boolean
function...but I didn't. Thanks for the conversation, this code works in
V13 (what I have open right now):
C_BOOLEAN($0;$exists)
C_TEXT($1;$set_name)
$set_name:=$1
Error:=0
ErrorHandler_Install ("ErrorHandler_SuppressError")
C_BOOLEAN($is_in_set)
$is_in_set:=Is in set($set_name)
ErrorHandler_InstallPrevious
$exists:=Error=0 // You could test for error 39 to be a bit more specific.
$0:=$exists
...this assumes that you install a valid error handler, otherwise you'll
get some other error...
