[plt-scheme] Re: My Scheme Probelm (fwd)

Hi HZBilal,

Please don't email me directly; I may not necessarily have the time to 
help you, or I may not be the best person to help you.  See:

     http://catb.org/esr/faqs/smart-questions.html#noprivate

for reasons why asking for help in private email is counterproductive 
compared to asking a forum.  I am forwarding your question to the 
plt-scheme mailing list so you can get appropriate help.

Re: [plt-scheme] My Scheme ProbelmDear Danny,

Is it possible some how to use AND and OR with Scheme, or something 
similar to that? I.e. for example my code wants to check using an IF 
statement if its red OR black then do this ELSE do that? So looking at my 
sample code below, instead of repeating the code for both formals-in and 
formals-out, it would be good if i can make it check for either then pick 
up otherwise ignore. However, if it is not possible, then how can you do 
this, whether with IF statements or any other conditions? 
(pdg-vertex-set-traverse (pdg-formals-in pdg) ;; Looking through each PDG 
for input parameters.

(lambda(v)

(abs-loc-set-traverse (pdg-vertex-ids-decl-uses v) ;; Looking through vertices to check if its the right type.

(lambda(w)

(display (abs-loc-name w) out-port)

(newline out-port)

#t))#t))

(pdg-vertex-set-traverse (pdg-formals-out pdg) ;; Looking through each PDG for output parameters.

(lambda(v)

(abs-loc-set-traverse (pdg-vertex-ids-decl-uses v) ;; Looking through vertices to check if its the right type.

(lambda(w)

(display (abs-loc-name w) out-port)

(newline out-port)

#t))#t))

Thank you very much for your time and help.
HZBilal.

   Didn't you ask this exact question last week?

   You did get a response:

   http://list.cs.brown.edu/pipermail/plt-scheme/2006-October/014899.html

   If you didn't read it, please do.  I spent time reading that code, and I'd
   hate that effort to be wasted.
