Processes activities separately for
each BY group, producing a
separate calendar for each value of the BY variable.
- specifies the variable that the procedure uses to form BY
groups. You can specify more than one variable, but the observations in the
data set must be sorted by all the variables that you specify or have an appropriate
index. Variables in a BY statement are called BY variables.
When you use the CALID
statement, you can process activities
that apply to different calendars, indicated by the value of the CALID variable.
Because you can specify only one CALID variable, however, you can create only
one level of grouping. For example, if you want a calendar report to show
the activities of several departments within a company, you can identify each
department with the value of the CALID variable and produce calendar output
that shows the calendars for all departments.
- specifies that the observations are sorted in descending
order by the variable that immediately follows the word DESCENDING in the
- specifies that observations are not necessarily sorted in
alphabetic or numeric order. The observations are grouped in another way,
for example, chronological order.
When you use a BY statement, however, you can further divide activities
into related groups. For example, you can print calendar output that groups
departmental calendars by division. The observations for activities must contain
a variable that identifies which department an activity belongs to and a variable
that identifies the division that a department resides in. Specify the variable
that identifies the department with the CALID statement. Specify the variable
that identifies the division with the BY statement.
