See: <tt><ref id=".LOWORD" name=".LOWORD"></tt>
<sect1><tt>.IDENT</tt><label id=".IDENT"><p>
The function expects a string as its argument, and converts this argument
into an identifier. If the string starts with the current <tt/<ref
id=".LOCALCHAR" name=".LOCALCHAR">/, it will be converted into a cheap local
identifier, otherwise it will be converted into a normal identifier.
Example:
<tscreen><verb>
.macro makelabel arg1, arg2
.ident (.concat (arg1, arg2)):
.endmacro
makelabel "foo", "bar"
.word foobar ; Valid label
</verb></tscreen>
<sect1><tt>.LEFT</tt><label id=".LEFT"><p>
Builtin function. Extracts the left part of a given token list.
