After some experimentation, I'm satisfied that the NEC convention holds
true for the M100, also. Bit 1 of the directory entry flag byte should
be set when a file is "opened". 

So the Flag byte looks like:
7=Valid.............(0x80)
6=Ascii.............(0x40)
5=Machine-language..(0x20)
4=ROM...............(0x10)
3=Invisible.........(0x08)
2=reserved
1=Open..............(0x02)
0=internal use only

 
I still can't use MASDEL without cold-starting my m100 but hey, baby
steps.
