Notes: * Fields of DTA change dependent upon function call in progress
* The DTA cannot span a 64K segment boundary
* For compatibility with CP/M the default DTA is at offset 80h
in the PSP; this area is also used for the command tail. To
avoid collision, set another DTA (INT 21h/1Ah) or preserve the
command tail before using FCB function calls
* Some documentation has the STARTING CLUSTER at address 0Fh
instead of 13h ??? |
