Re: Dereferencing Mystery

You shouldn't use Switch.pm, it has subtle bugs.
What's the switch for here anway, all you're doing is execute one "case" after the other, there's no fall-through or anything that requires this execution out of a standard for-loop.
Running this codes gives the following output:

0  --HASH(0x82bfd04) Data_Directories_fetch
1  --HASH(0x828b9a8) Data_Directories_erase
2  --HASH(0x82bbf40) Program_fetch
3  --HASH(0x82bfcbc) Program_erase
4  --HASH(0x82bbec8) Configuration_and_Table_Files_erase
5  --HASH(0x815b734) Configuration_and_Table_Files_fetch
6  --HASH(0x82bbee0) Create_Database
7  --HASH(0x82bbe38) Load_Database
HASH(0x82bbf40)
Result: HASH(0x82bbf40)

Loading some values into the Program_fetch hash first gives:

0  --HASH(0x82bc21c) Data_Directories_fetch
1  --HASH(0x82bfd00) Data_Directories_erase
2  --HASH(0x8160c8c) Program_fetch
3  --HASH(0x82bc0f0) Program_erase
4  --HASH(0x82bfce8) Configuration_and_Table_Files_erase
5  --HASH(0x815b728) Configuration_and_Table_Files_fetch
6  --HASH(0x82bc12c) Create_Database
7  --HASH(0x82bfd84) Load_Database
HASH(0x8160c8c)
1 => 2
3 => 4
Result: HASH(0x8160c8c)
1 => 2
3 => 4

Which is exactly what I'd expect. What are you expecting to see?

There are ten types of people: those that understand binary and those that don't.

My second hash reference points to the same address as the first but, unlike yours, doesn't print out the values. The second is a DBM record on the drive. So, I think it's not resolved?	[reply]

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) [download] Edit: g0n - code tags	[reply] [d/l]
