compilation of subroutines without resetting calling sequence [message #71568]

OK, compiled procedure 'A' calls function 'B', but spends most of its
time in functions 'C-Z'.

Function 'B' has a math error somewhere, which I am trying various
things to get rid of. By setting !EXCEPT=2, I have lots of information
on where the screwup is occurring.

Once I get the spew from !EXCEPT=2, I manually interrupt the program,
which is at that point working through functions 'C-Z'. I make changes
to subroutine 'B', recompile it, and then '.continue' to see if the
changes worked next time through subroutine 'B'.

Except that doesn't work. '.compile' returns no exception, and
'.continue' works like one expects, but it won't actually recompile
the routine.

So, evidently it's the top-level routine that must be recompiled in
order to get changes to subroutines into effect, but if someone wants
to provide a more coherent explanation of what IDL is doing here, I'd
love to hear it.
