There are two sources - cross compiler (host - MS DOS/8086, target - Apple DOS/6502)
and self compiler (host and target - Apple DOS/6502). Compiled program must be placed
in file with name C.PRG, compiled result are saved in file C.COM. Apple DOS version
was tested in AppleWin 1.23 emulator (in Apple //e mode) and CiderPress 3.0.1 disk utility.
Compiler source code listed below may be compiled with
Tiny Context 1.18 (c.118), or with
Context but in second case seven modifications
of source coderequired:
char Temp [16640]; // Add before char Text [16384]; // Because memory models are different
word mul (word A, word B) is -> word mul (word A; word B) is
word div (word A, word B) is -> word div (word A; word B) is
word mod (word A, word B) is -> word mod (word A; word B) is
word Digraph(char C1, char C2) is -> word Digraph(char C1; char C2) is
word Emi3(word P, word W) is -> word Emi3(word P; word W) is

Apple DOS version are based on code listed above but has another I/O functions
and some other minor differences.
To load and run program use following commands
BLOAD C.COM, A3072
CALL 3072
File write function work incorrect and commented. Instead of compiler print plus character
and code size. To store compiled program on disk use following command:
BSAVE <FILE_NAME>, A$4F56, L<CODE_SIZE>
Note that this command write incorrect load address 0x4F56. Correct address 0x0C00 (3072) must be
present in BLOAD command.
The reason was never determined, and many years later the error could not be reproduced.
Write function uncommented and it seems to be working.
Files to be written to disk must have the following names:
C.COM#060C00
C.PRG#040000
The first two digits after the hash mark are the file type, the next four digits are the download address.
In the CiderPress program, you need to open the MASTER.DSK disk image included in the emulator and write
these two files to it.
In the emulator, open this disk image, then launch the emulator and run the commands:
BLOAD C.COM
DELETE C.COM
