Re: R: BIF's question.

["David Morris" <dmorris@xxxxxxxxxxxxx>]

John,

One strange thing is that you can't specify %len(fld) = *ZERO, you must specify 
%len(fld) = 0.  When I first saw this I thought it was such an obvious error 
that I 
didn't bother reporting it.  I guess it wasn't that obvious because it has been 
this 
way for quite a while.

Wrong,  It can assign a value with VARYING length fields,

C         EVAL %LEN(VARYING_FLD) = 5

A couple of other string handling BIF's like %SUBST, %REPLACE I think can
also be assigned(on the left side of = sign).
