Syntax

EXPCOLUMNLEN=column-length

Required Argument

column-length
specifies the length of the SAS column when expressions are used. Valid values are integers from 1 to a maximum SAS column size.

Details

When character data items are defined with expressions in an information map, the length of the resulting SAS column cannot be readily determined by the Information Maps engine. Use the EXPCOLUMNLEN= option to assign a value to the length of the column. This value can be tuned based on an understanding of the results of the expression and of the data involved.
