The picture characters Z and asterisk (*) specify conditional digit positions in the character value and can cause leading zeros to be replaced by asterisks or blanks. Leading zeros are those that occur in the leftmost digit positions of fixed-point numbers or in the leftmost digit positions of the two parts of floating-point numbers, that are to the left of the assumed position of a decimal point, and that are not preceded by any of the digits 1 through 9. The leftmost nonzero digit in a number and all digits, zeros or not, to the right of it represent significant digits.
Table 37 shows examples of zero suppression characters.

If one of the picture characters Z or asterisk appears to the right of the picture character V, all fractional digit positions in the specification, as well as all integer digit positions, must use the Z or asterisk picture character, respectively. When all digit positions to the right of the picture character V contain zero suppression picture characters, fractional zeros of the value are suppressed only if all positions in the fractional part contain zeros and all integer positions have been suppressed. The character value of the data item will then consist of blanks or asterisks. No digits in the fractional part are replaced by blanks or asterisks if the fractional part contains any significant digit.
