Hi, I am looking at RetroForth as a vehicle for accepting a port of an old Forth program I wrote many years ago.
The final target system is unlikely to be a Windows platform but I would like to use Windows for the initial development.
The original system had no standard OS as it ran on a dedicated Z80. I implemented a simple file system using 1 kb blocks.
I need to modify the file support to us 1 kb blocks instead of 512 byte blocks and understand how the interface with the OS operates.
It does seem to use some rather clever words and compiler techniques.
I should be able to sort out the importing of functions from kernel32 as I have a Microsoft Visual Studio development system.
If this type of interface with an OS has been documented more fully some where else, then please can you give me a few links.
Thanks, Paul.
I think I now know how functions are imported from kernel32. To add the Beep function I enter:
kernel32 ( to select the kernel32 vocabulary )
2 import Beep ( to seltup the two parameter function interface )
4000 1000 Beep ( plays a 4 KHz tone for 1 second and returns a positive value if the function call was successful )
I guess that with a little more effort on my part, I will understand why blocks are 512 bytes and hopefully how to change it to 1 kb.
Paul.
