Tidy up when done
These days in the 4D_Tech mailing list:
do you clear local variables after you're done with them?
I have to process close to a million records. The process is a method that creates big local variables. Big arrays, big text vars. But it's a sub-call, so after each call the locals will get cleared auto-magically.
I'm semi-superstitious and am thinking I should clear them myself at the end of the sub-method.
Silly? Paranoid? No harm? Great idea?
Good question, isn't it?
I'm trough with that! Why, because it's easy now. All I need to do is call Gen_EmptyContent and send all those Vars and fields which need to be emptied like this:
This clears a bunch of variables, takes care about types and even tries not to invoke 4Ds error-handling like here
ja, si, oui, はい
