- 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.
