Parse string variables
----------------------

    ^strparse^ strvar [^if^ exp] [^in^ range] , ^g^enerate^(^stub^)^
    [ ^p^arse^(^parsestr^) noTrim^ ]

Description
-----------

^strparse^ parses a string variable into one or more string variables
based on a parsing character, by default blank space(s).  It is useful for
separating words in a string variable, although parsing can be done using
any substring, not just spaces. 


Options
-------

^generate(^stub^)^ is not optional.  It specifies the beginning
    characters of the new variable names: stub^1^, stub^2^, etc.

^parse(^parsestr^)^ specifies that, instead of spaces, parsing should
    be done using parsestr.  For example, if ^parse(,)^ is specified then
    ^"1,2,3"^ becomes three string variables with values ^"1"^, ^"2"^ and ^"3"^.
    parsestr may be more than one character: if so, the entire sequence 
    is used as one, not as separate parsing characters.

^noTrim^ specifies that the original string var should not be trimmed
    of leading and trailing spaces before being parsed.


Examples
--------

    . ^strparse name, gen(nameN)^

    applied to ^"John Smith"^ creates ^nameN1^ = ^"John"^ and ^nameN2^ = ^"Smith"^

    . ^strparse stuff, gen(junk) parse(X/)^

     ^"abcX/def"^ becomes ^junk1^ = ^"abc"^ and ^junk2^ = ^"def"^ 
     
     ^"abc X / def"^ becomes ^junk1^ = ^"abc X / def"^
