The switch is just a way to associate the hash addresses with a descriptive string. Perhaps not the bast way but the mystery is that I get the following.
The loops are referencing the same hash but what I can't explain is why only the first loop works?

0  --HASH(0x18b73bc) Data_Directories_fetch
1  --HASH(0x18a50f0) Data_Directories_erase
2  --HASH(0x18b7518) Program_fetch
3  --HASH(0x18b74e8) Program_erase
4  --HASH(0x555250) Configuration_and_Table_Files_erase
5  --HASH(0x555280) Configuration_and_Table_Files_fetch
6  --HASH(0x18b8224) Create_Database
7  --HASH(0x18b8254) Load_Database
HASH(0x18b7518)
/reba/shlib     => Y
/airreba/procs  => Y
/xcape/bin      => Y
/reba/bin       => Y
/airreba/tables => Y
/reba/onetime   => Y
/xcape/bin_util => Y
/reba/perlib    => Y
Result: HASH(0x18b7518)
