A..4 Reserved words in the CQP language

Reserved words cannot be used as identifiers (i.e. corpus handles, attribute names, query names or labels) in CQP queries and interactive commands.

new in CQP v3.4.13: Reserved words can now be used as identifiers if they are quoted between backticks whenever mentioned.
> show +`no`;'
> `MU` = [lemma = "meeting|union"];
> group `MU` match lemma;
> [`size` = "\d{5,}"];
Quotes are neither required nor allowed in label definitions and qualified label references.
> left: [pos = "NN"] "after" right: [pos = "NN"] :: left.lemma = right.lemma;
The usual rules for identifiers still apply, so e.g. size `007`; will not be accepted.

The full list of reserved words is>:

a: asc ascending

b: by

c: cat cd collocate contains cut

d: def define delete desc descending diff difference discard dump

e: exclusive exit expand

f: farthest foreach

g: group

h: host

i: inclusive info inter intersect intersection

j: join

k: keyword

l: left leftmost

m: macro maximal match matchend matches meet MU

n: nearest no not NULL

o: off on

r: randomize reduce RE reverse right rightmost

s: save set show size sleep sort source subset

t: TAB tabulate target target[0-9] to

u: undump union unlock user

w: where with within without

y: yes
