HyperTalk, like C and Pascal, ignores spaces in valid expressions.  The
only time spaces become important is when the expression is invalid and
HyperTalk interprets it as an uquoted literal.  For example:

  go to stack clip art

is interpreted as

  go to stack "clip art"

Note that because stack names can only occur at the end of a line,
HyperTalk will accept multiple token unquoted literals.  In most
other cases, it will only take single token uquoted literals.  For
example:

  put field date into x

is interpreted as

  put field "date" into x

but 

  put field date of birth into x

would cause a syntax error because HyperTalk cannot recognize
multiple token unquoted literals within a line.  In general,
use of unquoted literals is strongly discouraged since if you
later define a variable of the same name then your script will
begin behaving differently.
