Re: Error in the EVAL Statement? (when + is used more than once)

["Peter Dow" <maillist@xxxxxxxxxxxxxxx>]

Hi Peter,

The plus sign ("+") is both a unary operator and a binary operator, i.e. it
can have one or two operands.  When used as a unary operator, it simply
maintains the value of the operand.  As a binary operator, it adds numeric
operands, and concatenates character operands.

The asterisk ("*") is a only binary operator, and requires two operands, so

c    eval amount2 = amount1 *
c             * 500.00

is not valid syntax, since an operand is missing.
