LET Free_Syntax

            The LET command may be omitted if no option is present, and  if  the
        SIC  syntax  is  set to FREE. In this case, the = sign is mandatory.  In
        FIXED syntax, the LET command is compulsory, but the = sign optional. In
        FREE syntax, commands lines like
               A[I,J] = SIN((2*I+J)/PI)
        where A is a known variable, are recognized as assignement and automati-
        cally expanded to the equivalent FIXED syntax
               LET A[I,J] SIN((2*I+J)/PI)
        In case  of conflict between a variable name and  a  (complete)  command
        name,  an  error  message  is issued. Free syntax cannot be used for the
        LET /WHERE command. Command SIC SYNTAX [Free|Fixed] can be used to  tog-
        gle between Fixed and Free syntax if needed.
