• The content of C+1 (Total characters) specifies the number of ASCII char-
acters after conversion including the sign symbol, numbers, decimal point
and spaces.
• The content of C+2 (Fractional digits) specifies the number of digits (char-
acters) below the decimal point.
The ASCII text is stored in D and subsequent words in the following order:
leftmost byte of D, rightmost byte of D, leftmost byte of D+1, rightmost byte of
D+1, etc.
