RE: Import in procedure ?

["Nicolay, Paul" <paul_nicolay@xxxxxxxxx>]

Hi Barbara,

I always found the Import/Export stuff for variables bizarre in the first
place :-)

I now corrected the Import (moved it to module level) and it works fine,
however I don't see the point of doing an Import on a variable which only
has a meaning within a certain procedure at module level ?

BTW, why do you consider the scope 'global to the application' ?  To me, I
feel one can only have scope when a variable does exist.  Apart from the
export, I don't see any variable that does exist at application level... but
I do have one at module level (still better sounds procedure level to me).

Kind regards,
Paul

Paul, names are imported and exported at the module level in ILE.  I
confess it never even crossed my mind to allow importing from
outside the module directly into a local variable.  Now that I do
think about it, it seems to me that it would be somewhat bizarre
to have a variable whose scope was both local to a subprocedure
and global to the application, but not global to the module.
