'i have trouble posting this program, apparently it has too many
'lines to be loaded in one part.
'so i try to post it in three parts now.

'[CODE]
'simple operating system in powerbasic for dos
'
'runs in real mode and is to some extend compatible to dos
'by implementing often used dos functions to get dos
'applications to run.
'
'supports a floppy disk and root directory.
'does not have file access functions for application programs.
'cannot call basic code from an isr. would have
'to convert the disk functions to assembler for that.
'
'will run pbdos, assembler, turbo pascal, turbo-c and ms-c programs.
'i could print "hello world" in these languages and run some games.
'will not run quickbasic programs.
'
'intended as a sample, not all functions are tested completely

'use with the bootloader already posted in this forum:
