[MacPerl] Location of MAIN code relative to subroutines

[Ero Brown <ero@fiber.net>]

I seem to ben having a problem regarding the placement of "MAIN"
code relative to subroutines.

When I execute the following script, the variable $TIME_OFFSET
doesn't seem to have value in the "ParseFile" subroutine.

However, if I move the location of my "MAIN" code (or actually
just the code snip in "MAIN" where $TIME_OFFSET is defined) to
a position before my subroutines, this script appears to work
correctly.

Is this a MacPerl bug, or am I missing something here?
I'm currently using MacPerl 5.2.0r4.

Thanks,

Ero Brown
