Here's a full example (from my lDebug/assorted/tests/ directory, wasn't yet in any repo) that builds a new child PSP from the current PSP, DUPs the file handles to use in the child, sets this child PSP as active, enters protected mode, then returns back to the original process in 86 Mode. (Plus, it shows some callback usages.) It builds with nasm dpmipsp.asm -f bin -o dpmipsp.com -l dpmipsp.lst
