- The DBDIR routines demonstrate how to call an assembler
- subroutine from dBASEII. There are a number of restrictions! Briefly,
- you can load an assembler routine above location A400 hex, as long as
- you don't do any sorts!!!!! You have available to you the memory space
- from A400 hex to the top of your TPA (on mine it is E400 hex, on a 64K
- system).
- The following files are required:
- - dbdir.cmd
- - asciidec.cmd
- - dbdir.asm
- The .asm file is Z80 code which was assembled using M80/L80,
- and does a not very efficient method of getting the directory entries,
- but it works.
- Hope this helps explain a not too well documented command
- in dBASE. Any comments concerning these routines can be left on this
- BBS, and if you make any wonderous enhancements, and would like to
- share them, please leave them on this BBS also.
