Q: What's a pdb file?

A: It's a data file for an application.  All PalmOS data files are
   pdb databases.  Doc files are the most common, but there are many
   other types of pdb databases.  The type of a database is indicated
   by the creator signature: 4 characters located at bytes 64 though 68
   (0x40) of the pdb file.  You can check them out with a hex dump
   utility on the desktop PC, or on the Palm handheld itself using an
   app such as ypfile, insider or FlashPro.

   Here are some of the more common creator signatures for applications
   that often have multiple named databases:

   REAd	Doc,AportisDoc	(first doc reader, converted text document reader)
   TlPt	TealDoc		(TealDoc document reader)
   ToGo	iSilo		(iSilo converted html document reader)
   RTFV	RichReader	(RichReader converted rtf document reader)

   LSdb	List    	(freeware/open source 3 column database)
   JBas	JFile   	(database)
   Mdb1	Mobiledb	(commercial database)
   PmDB	HanDBase	(commercial relational database)
   DBOS	db      	(freeware/open source database)
   JFil	jfilepro 	(database)
   
   Sprd	Quicksheet	(spreadsheet)
   PiMC	MiniCalc	(spreadsheet)
   PXXL	Abacus  	(spreadsheet)
   map1	HandMap  	(map viewer)
   SSsc	SynCalc		(calculator)
   PktC	PocketC		(C tokenizer/interpreter)
   Fotz	Frotz		(zip/adventure interpreter)

   less common:

   ZIPp	ZIP     	(zork/adventure interpreter)
