Assigning Pcell parameters by reading vales from file

Hello,

I wrote short code to read a file(CSV) and then I am storing the vlaues in a respecive variable.

Example:

CSV FILE:

w   1.1

l 0.9

grid 0.35

My code:

while( str = lineread(file)
case( car(str)


(w

  if(cdr(str)

  then

  w = cadr(str)
  else error("w not defined in %s file" file)
  ); end if

);w

(l

  if(cdr(str)

  then

  l = cadr(str)
  else error("l not defined in %s file" file)
  ); end if

);l

and then I will use these values to define the parameters in pcell with same variable 

;;FORMAL PARAMETERS

(

(w float w) ;; This is wrong, I want to skip this 

(l float w)

)

As the above method is not correct but I have already stored the value in "w" and "l" so how Can I define my formal parameters with the values that I have read from file ?

will this work:

(

(w)

(l)

)

or is there any way I create a database and directly create the object in database variable and store values like

 if(cdr(str)

  then

  myObj~>w = cadr(str)

and then while defining pCell parameters I can write

(

(w float myObj~>w)

(l float myObj~>l)

)

Which method is suitable can anyone guide me ?

Thanks and sorry for the bad explanation.
