4100 The total number of digits specified by (S1) is outside the following ranges:
• When the STR instruction is used: 2 to 8
• When the DSTR instruction is used: 2 to 13
The number of digits for a part of the decimal fraction specified by (S) +1 is
outside the following ranges:
• When the STR instruction is used: 0 to 5
• When the DSTR instruction is used: 0 to 10
The relationship between the total number of digits specified by (S1) and the
number of digits in the decimal fraction specified by (S1) +1 is not as follows:
• Total number of digits -3  Number of digits in the decimal fraction
The number of digits specified by (S1) is smaller than the number of digits of
the BIN data + 2 specified by (S2)
((Number of digits of (S1) < Number of digits of the BIN data at (S2) without a
sign + number of digits of a sign (+ or -) + number of digits of decimal point
(.))
