                INT 21,26 - Create New Program Segment Prefix


       AH = 26h
       DX = segment address of new PSP


       returns nothing


       - allocates memory for a PSP and copies current PSP there
       - used before DOS 2.x to spawn a child process
       - the application is responsible for allocating any memory
         necessary for the child process
       - INT 21,4B (EXEC) is now the recommended method for starting
         a child process, so this function should be avoided


       - see also INT 21,55
