PSP manipulation from DPMI programs (Developers)
Hello Laaca,
By the way... depending on what Free Pascal's DOS extender does, you might be able to build the child process's new environment variable block in extended memory (without having to purposely place it into base memory (!)). The key thing will be to check how int 0x21
, ax
= 0x4b00
is handled.
Thank you!
