#ifdef INFORMATION

A token is nominally a contiguous collection of characters broken off by tab or space(since return and newline are stripped off).

Tokens to include whitespace are encased in doublequotes.

Characters with reserved status automatically also break into individual tokens and to include them you must put \ before them.These include :

[]() {} always and separate into individual tokens except for _(_[_{

< > and << >> are reserved, but only when at start or end of token.Allowed comparisons embedded.As is <= and >=

Tokens ending with ' or 's break off(possessive) in patterns.

Tokens starting with prefix characters ' or ! or _ keep together, except per reserved tokens. '$junk is one token.

Variables ending with punctuation separate the punctuation.$hello.is two tokens as is _0.

Reserved characters in a composite token with _ before or after are kept.E.g.This_(_story_is_)_done

You can include a reserved tokens by putting \ in front of them.

Some tokens revise their start, like the pattern tokens representing comparison.They do this in the script compiler.
