Format: Wid[en] [condition]The WIDEN command restores the data set after a NARROW command. If no condition is given then all the the rows are included. If a condition is given, then all the rows previously included will remain, but any others that comply with the condition will be included in addition.
Examples:
Enter command - WIDENIncludes all rows.
Enter command - wid c3=4Adds in rows for which third entry is 4.
Enter command - n c2>7 ... ... Enter command - wid c2<3Now data set includes all rows whose second entry is greater than 7 or less than 3.
Example output:
Widening data set to include all lines
Widening data set to include lines for which C2<7
Comment
In practice it is quite rarely helpful to use WIDEN with a condition. Generally one just uses it on its own and then uses NARROW to reduce the data set again. The rows remaining after a NARROW and then a WIDEN command are those for which either condition is true. Note that the order in which the NARROW and WIDEN commands are issued is important.
