Question: Invalid left hand side in assignment of a proc


The two attached programs are such that the "kaput" version uses a procedure to draw the letter V, with the option of a flat top or pointed top.  The last parameter, s, takes on values "p" or "f" for pointed or flat respectively. - but I get error messages.  The Letter_V_working programdoes not use a proc, but works.  Where is the error?

  Thanks in advance for any help.
