IDENTPROPS	As you will have noticed, the POP11 system
treats words differently when compiling. For example:
 	: VARS X; 3 -> X;
.br
is permissible, whilst:
 	: VARS IF; 3 -> IF;
.br
is not.
This is because IF is a 'syntax` word, as you can discover by executing:
 	: IDENTPROPS("IF") =>
.br
Possible value for IDENTPROPS are:
.in +5
.ll -5
1) UNDEF for a word not yet declared.
.br
2) SYNTAX for a syntax word (IF, AND, CLOSE etc)
.br
3) 0 (zero) for a 'normal` variable (HD, TL etc)
.br
4) Any other integer for an OPERATION word, (+, -, <> etc)
The integer is the operation's precedence.
.br
5) MACRO for a macro.
.in-5
.ll +5
