Code:
type ab as string * 6c as string * 6end typedim d as aswap d.b,d.c
And I can tell the problem is down to trying to exchange 2 6-byte string values with swap, because I introduced the command into another one of my programs and when i tried running it, the message at the bottom left was stuck on "binding" and sometimes the screen would either freeze up, or I get booted back to the DOS prompt without the IDE screen being erased first.
