Zsh hackers,
I am attempting to return a path name from the following function.
prep_directories()
{
output_directory="/var/adm/backup/${1}_${2}"
backup_log="${output_directory}/backup.log"
backup_lis="${output_directory}/backup.lis"
return $backup_log,$backup_lis
}
prep_directories 20000330 WEEKLY
Executing this script results in the following error.
prep_directories: bad math expression: unbalanced stack [75]
I assume it has something to do with the slashes (/) found in the string
that it is attempting to return.
Any and all suggestions will be greatly appreciated.
Thanks,
Allen Belk

You cannot return string. return expects arithmetic expression as
status. I agree, that message is a bit weird ... what exact vesion do
you have?
What you try to do? Either output result using echo or print builtin:
print $backup_log,$backup_lis
in this case you can do something like
DIRS=$(prep_directories 20000330 WEEKLY)
or you can set parameter explicitly in function:
DIRS=$backup_log,$backup_lis
