Notes:

(BINARY, BIN, DECIMAL, or DEC) and (FIXED or FLOAT) and (precision, scale) can be specified in any order.
A picture-string in the form '9...9V9...R' indicates a numeric host variable. The R is required. The optional V indicates the implied decimal point.
A picture-string in the form 'S9...9V9...9' indicates a sign leading separate host variable. The S is required. The optional V indicates the implied decimal point.
