proc usedata


Version 2.41 Mar2009

Scripts


Manual page for proc_usedata(PL)

Select the current data set for plotting. Typically used when additional derivations have been produced by proc processdata or tabulate, in order to return to the original data set, or to "pop back" to an earlier data set on the stack.

Note: proc getdata always clears the stack and its result becomes dataset 1.


Attributes

If no attributes are specified, default is pop: all.

pop     all | n

If all, pop back to the original data set (proc getdata). Otherwise, pop back n data sets. After this is done, data sets above the current one in the stack are removed and unavailable.

originaldata     yes

Equivalent to pop: all

fieldnames     namelist

Set any data field names that will be in effect. Field names are not retained in the data set stack structure, so if a data set that had field names is made the current data set, the field names must be respecified here using this attribute.

element     n

Stack element n becomes the current data set for plotting. Discontinued as of version 2.40.


Example

   #proc usedata
     original: yes
