HEAP itself is not part of ANS94 / I do not find it there at least.

Looking at the code that uses HEAP directly, most of them use the
sequence "heap e@" so changing it to a real VALUE should be an
easy task.

Oh, don't worry too much. "most" code use ALLOT (that is part of ANS).
heap
is pretty much amforth specific. If no-one objects, I'll review most
of the EEPROM
based variables and turn them into real VALUEs.

: allot heap + to heap ;

(The sequence could be factored into a word of its own: add-to, ,
(comma) has a similiar
code)
