st: RE: Syntax syntax
After this syntax, what is specified
in -preffect()- will be visible as `preffect'.
This will be a string (emphatically not
a string variable). The ` ' are essential.
by itself will be interpreted as
a reference to a variable -preffect-,
in fact to -preffect-, which evidently
you don't have.
If you don't have anything compulsory before
the options the syntax should be
syntax [, PREffect(string)]
