[s1mp3-dev] 2nd stage and disptext-large

[Bluechip]

Technically Z80-asm does not have any such thing.
But most assemblers will implement such.
My Z80-asm used to use EQU.
Whatever the syntax, it IS possible, and SHOULD be done :)
I suggest that if we don't have an assembler with such features as 
EQUates and INCLudes we write our own.
