Len (Length Integer, [Decimal Integer])
Parameters
F2
Required. Must be numeric and can contain one of the following: an array, array element, field, figurative constant, literal, named constant, subfield, or table name.
Result
Required. Can contain one of the following: an array, array element, field, subfield, or table name.
Adj
Optional. Indicates half-adjust. Use Adj (RNDUP) if you wish to round up the value, or use Adj (TRUNC) if you wish to truncate the value of Result . *TRUNC is the default.
Pos
Optional. Turned on if the value of Result is a positive number.
Neg
Optional. Turned on if the value of Result is a negative number.
Zero
Optional. Turned on if the value of Result is zero.
Type
Optional. Can be any of the types listed. *NONE is the default. See Type Parameter for further information.
Len
Optional. Defines the length of the field. If Len is decimal (3,1) *ZONED is assigned as the default.
Depending upon the Type specified, the Len parameter may be required. For instance, Types of *CHAR, *PACKED, *ZONED will require a Len . A compiler message will display if the Len parameter is needed.
Remarks
F2 is subtracted from a field of zeros. The difference, which is the negative of F2 , is placed in Result . You can use the operation to change the sign of a field. Half-adjust can be specified.
