|
; History
|
|
|
|
; 2017-02-10: Extract from the main file: entry points,
|
|
; variables and sector buffer addresses.
|
|
;
|
|
; 2017-03-08: Rename `trdos_variable.file_size` to
|
|
; `trdos_variable.stream_or_file_size`.
|
|
;
|
|
; 2017-03-09: Improve name of variable 23814.

|
|
; (0x3C03) is out of the range of addresses that make the TR-DOS
|
|
; memory page in (0x3D00..0x3DFF). Probably the confusion was caused
