#46 closed bug (worksforme)

problem with ring variables in subroutines

Reported by: Oleksandr Owned by: hannes
Priority: major Milestone: 3-1-1

Description

There is a problem in using ring variables (ideals etc.) in subroutines when these variables were not exported and ring was suppled as an argument, see attachments.

note that listvar(); still lists them but they appear to be undefined! therefore it's likely to be a bug.

All local variables will be removed at the end of a procedure. This applies also to the ring AND to the objects in that ring. Objects from a ring can only survive, if both the ring and the object are global (exported). Seems to apply to this ticket (example is difficult to understand)
