DISPLAY DICTIONARY.
- The
GET and FREQUENCIES commands are executed.
- The
RECODE, COMPUTE, and VARIABLE
LABELS commands are transformations. They do not affect
the data until the next procedure is executed.
- The
CLEAR TRANSFORMATIONS command discards the RECODE, COMPUTE, and VARIABLE LABELS commands.
- The
DISPLAY command
displays the working file dictionary. Data values and labels are exactly
as they were when the FREQUENCIES command was executed. The variable INDEXQ does not exist because CLEAR TRANSFORMATIONS discarded the COMPUTE command.
