Would you share the code ?
Thanks

Just to clarify, the presence of line numbers doesn't of itself result in a slowing of the program. It's only their use as the destination of a GOTO, GOSUB or RESTORE that is (relatively) slow.
So you can leave the line numbers, if you wish, but adding labels as the destination of branches can speed things up a little.

The code to strip out line numbers and replace them with labels? Sure. To use it you have to paste your code to a text file, save the altered version back to a text file and then copy it back into LB or LBB.
...but before I do, are there any instructions other than GOTO GOSUB THEN and ELSE that can be followed by a line number?

I used to use REMLINE.BAS (easily googled) to remove extra line numbers. That is, ones not used as destination.
(again, this will leave exactly only line numbers which slow down LBB  )

Yes, I was sure someone must have written something similar

As I stated in my earlier reply, RESTORE is another. In fact it's the only use of a label which doesn't have a better alternative. GOSUB can be replaced by CALL, event handlers can use SUBs, and GOTO is avoidable altogether by using DO or WHILE. Oh, and ON ERROR GOTO can be replaced by TRY...CATCH!
