  *				from the first non-blank character of

  *				the word (which may be " or {) up to but

  *				not including the space, semicolon, or

  *				bracket that terminates the word. 

  *				NumComponents counts the total number of

  *				sub-tokens that make up the word.  This

  *				includes, for example, sub-tokens of

  *				TCL_TOKEN_VARIABLE tokens.

  * TCL_TOKEN_SIMPLE_WORD -	This token is just like TCL_TOKEN_WORD

  *				except that the word is guaranteed to

  *				consist of a single TCL_TOKEN_TEXT

  *				sub-token.

  * TCL_TOKEN_TEXT -		The token describes a range of literal

  *				text that is part of a word. 

  *				NumComponents is always 0.

  * TCL_TOKEN_BS -		The token describes a backslash sequence

  *				that must be collapsed.	 NumComponents

  *				is always 0.

  * TCL_TOKEN_COMMAND -		The token describes a command whose result

  *				must be substituted into the word.  The

  *				token includes the enclosing brackets. 

  *				NumComponents is always 0.

  * TCL_TOKEN_VARIABLE -		The token describes a variable

  *				substitution, including the dollar sign,

  *				variable name, and array index (if there

  *				is one) up through the right

  *				parentheses.  NumComponents tells how

  *				many additional tokens follow to

  *				represent the variable name.  The first

  *				token will be a TCL_TOKEN_TEXT token

  *				that describes the variable name.  If

  *				the variable is an array reference then

  *				there will be one or more additional

  *				tokens, of type TCL_TOKEN_TEXT,

  *				TCL_TOKEN_BS, TCL_TOKEN_COMMAND, and

  *				TCL_TOKEN_VARIABLE, that describe the

  *				array index; numComponents counts the

  *				total number of nested tokens that make

  *				up the variable reference, including

  *				sub-tokens of TCL_TOKEN_VARIABLE tokens.

  * TCL_TOKEN_SUB_EXPR -		The token describes one subexpression of a

  *				expression, from the first non-blank

  *				character of the subexpression up to but not

  *				including the space, brace, or bracket

  *				that terminates the subexpression. 

  *				NumComponents counts the total number of

  *				following subtokens that make up the

  *				subexpression; this includes all subtokens

  *				for any nested TCL_TOKEN_SUB_EXPR tokens.

  *				For example, a numeric value used as a

  *				primitive operand is described by a

  *				TCL_TOKEN_SUB_EXPR token followed by a

  *				TCL_TOKEN_TEXT token. A binary subexpression

  *				is described by a TCL_TOKEN_SUB_EXPR token

  *				followed by the	TCL_TOKEN_OPERATOR token

  *				for the operator, then TCL_TOKEN_SUB_EXPR

  *				tokens for the left then the right operands.

  * TCL_TOKEN_OPERATOR -		The token describes one expression operator.

  *				An operator might be the name of a math

  *				function such as "abs". A TCL_TOKEN_OPERATOR

  *				token is always preceeded by one

  *				TCL_TOKEN_SUB_EXPR token for the operator's

  *				subexpression, and is followed by zero or

  *				more TCL_TOKEN_SUB_EXPR tokens for the

  *				operator's operands. NumComponents is

  *				always 0.
