    Ahem. The Stupidest Assembler Trick I Ever Saw Was One Written By
The R*** M******** Corporation For The TRS model 16 [already you are
getting the heebie-jeebies, i can tell :-) ]


    In This Gobbler Of A 68k Assembler, Spaces Were Significant In
Symbols. You Had To Terminate A Symbol With TWO Spaces, Or A Tab, For
Example:


this is a valid symbol:
jmp this is a valid symbol


    When I Saw This Actually Assemble, I Was Dumbstruck. I Still Stand
In Awe Of The Mind (Well, Probably A Committee) That Hatched This
Thing. I Assume That The Same Parties Later Moved On To X.500, But
That'S Just Idle (Well, Nasty) Speculation
