Hello: puts aString <<< no error printing aString here process(aString) ..... .... def process(aString) puts aString <<< error printing aString here end The error is: Exception: cannot convert Class into String What would it cause for aString to become a Class? Thanks! basi

hello, this code is not complete, so it is difficult to guess why aString inside the method is Class. konstantin "basi" <email@example.com> wrote in message news:firstname.lastname@example.org...

Yes, it is incomplete. I was illustrating that the variable aString is of type string just before calling the method, and right inside the method, in the very first command, it is diagnosed as a Class. -- I renamed the parameter aString in the method definition. That does not work. -- I moved the order of calling the method earlier/later in the call sequence. No dice. -- I retyped the line. Didn't work. No that I expected these to make a difference. I redefined aString inside the method, thus: def process(aString) aString = "ohmy" puts aString end It works, but doesn't solve the problem. I wonder what kind of statement that I might have made somewhere in the program that would turn a string variable into a Class? Thanks! basi

Nobody can answer without concrete code.

Hi, I found the problem. I should convert the value to a string: Wrong (for my purpose) aString = workStrings I got it to work with: aString = workStrings.to_s Cheers, basi

even workStrings[0,1] will work too. 0 is the start position and 1 indicates how many chars to read from that position unlike C, in ruby string returns the ascii value of the char at positon 0 and not char.

Thanks. This can come in handy, too. basi
