Edit masks determine how a numeric field will be formatted during output. If no edit mask is specified, Internet Basic supplies a default edit mask: leading zeros are suppressed, a decimal point is printed along with all leading and trailing zeros to the right of the decimal point, and a trailing minus sign is printed for negative values.

User-supplied edit masks may contain three parts: a leading character, the body characters, and trailing characters.

Leading character | Purpose |
---|---|

$ | Prints a dollar sign immediately before the first non-zero digit in the numeric field. The dollar sign floats from left to right, according to the location of the first non-zero digit. |

( | Prints left parentheses immediately before the first non-zero digit in the numeric field only if the field contains a negative value. The left parenthesis must be paired with a matching right parenthesis as the trailing character. |

Body characters | Purpose |
---|---|

0 | Represents a single digit of the numeric field. Prints zeros if the digit is zero-valued (including leading zeros), or digits 1 through 9 according to the value of the numeric field. |

# | Also represents a single digit of the numeric field. Prints digits 0 through 9 according to the value of the numeric field, but DOES NOT print leading zeros. |

* | Represents a single digit of the numeric field. Prints an asterisk in that position if the value of that position is zero. Used for asterisk fill of leading zeros. |

. | Separates integer portion of the numeric field from the decimal portion. Prints a decimal point in that position. Note: The decimal point cannot be used as the last character in an edit mask. |

, | Separates groups of digits on the left side of the decimal point. Prints a comma in that position. Will not print if leading characters are zero. |

Two basic rules determine the operation of edit masks:

- The first "digit character" in the body of the edit mask þ 0,
#, or * þ is used as the "fill character."
The fill character fills from the left of the numeric field to the first non-zero position.

If the edit mask is a string variable, the fill character may be virtually any character (other than a comma or decimal point).

- The significant starting position is determined by either:
a. the first non-zero digit in the data (from the left), or
b. the first position after the first 0 in the edit mask.

Edit masks must contain a trailing character. The following options are available:

Trailing character | Purpose |
---|---|

+ | Prints a plus sign after positive numbers, or a minus sign after negative numbers. Always prints a sign. |

- | Prints a trailing blank after positive numbers, or a minus sign after negative numbers. |

DR | Prints DR after positive numbers, or CR after negative numbers. Indicates "debit" or "credit." |

CR | Prints two blanks after positive numbers, or CR after negative numbers. |

) | Prints a right parenthesis after negative numbers, a blank space after positive numbers. Must be paired with a left parenthesis leading character. |
