INT 21h/AH=4B

[Robert Pengelly]

Can anyone tell me what needs to be passed in the Parameter Block. I've found http://www.delorie.com/djgpp/doc/rbinter/it/90/15.html which says:

02h DWORD pointer to command tail to be copied into child's PSP

When it says tail end of the command do they mean something like "command.com /?" or just "command.com"? Also, in a 16-bit OS the tail end will only be 2 bytes so what (if anything) goes into offset 4 and 5?
