Can you point me to the source code for the latter?

The source code in 4.0 is not the multitasking version - I
can see in src/dos/exec.asm line 154:

CMP AL,3 ; only 0, 1 or 3 are allowed
JNA exec_check_2

that it is non-multitasking, which would explain why I
can't find any sign of "NE".

Thanks. Paul.
