A Job File Number Table (JFT) entry is
assigned to each open file system object within a process. The JFT provides
a cross-reference to the handle for the corresponding SFT.
The JFT is locatable from the PTDAfield
JFN_pTable (PTDA +0x5b8 (H/R: +0x5b0)) for each process.
The JFT is initially allocated within the PTDA at label JFN_Table
(PTDA +0x35e) with 20 entries. If this is expanded by use of
the DosSetMaxFH then JFN_pTable is updated to point to the
new table.
