Sample program
Converting to ASCII Text in Decimal Notation
When CIO 0.00 is ON in the following example, FSTR(448) converts the floating-point data in D1 and
D0 to decimal-notation ASCII text and writes the ASCII text to the destination words beginning with
D100. The contents of the control words (D10 to D12) specify the details on the data format (decimal
notation, 7 characters total, 3 fractional digits).
