It will run on Windows XP in compatability mode.

Actually there is a copy of MapleV r 4 on the web somewhere.  I came across it last week.  Can't find it now though.

It would be advantageous to point here where some example data is located.

I need to assign after I read it in.

I need to assign after I read it in.

better example

test.txt file contains (b, Einstein once said "Everyone is  genius", in a famous quote.)

a:=readline("c:/test.txt")
                            a:=" (b, Einstein once said "Everyone is  genius", in a famous quote.)"

The reason to use parse is so that I can use assign but the extra quotes foil the attempt.

If Maple explicitly knows there is a backslash behind quotes within quotes it will be okay as your example shows.

If I change the test.txt file to read a:="Einstein once said Everyone is a genius, in a famous quote." which is a proper Maple statement it is fine until I add quotes within the quotes.

for example

test.txt file contains following text :  Einstein once said "Everyone is a genius", in a famous quote.

a:=readline("c:/test.txt")
                                          a:= "Einstein once said "Everyone is a genius", in a famous quote."

parse(a)

Error, incorrect syntax in parse: missing operator or `;` (14)

Copying the params to a simple text and reading it in is the easiest way to do it. 

Suppose we have a Maple .mw file containing only our parameters.  Yes, of course why not just enter the parameters in a text file instead and just read them in as PatrickT mentions.  Well I just wanted to see how hard it would be to extract the variables from the created mw file from maple, just a lot of text manipulation is required. 

Suppose we have our param.mw file containing just these variables.

a := 5;
b := 5*x+3*y^2;
c := cos(x)^2;
d := 7/(3*I);
e := diff(sin(x), x);

Here is a procedure that extracts those parameters
