in the output window the ‘unscored’ label appears without truncation.
Because when assigning a character label in a
dataset, the length of the first evaluation of the
label will be applied to all labels.
I don't understand it,what does the first evaluation mean here? for me
the length of '670-' is shorter than 'unscored'. |

发帖数: 535 | 3 No. If you use 'if then' you will get truncated 'unsco' for unscore.
But format will allow the full length 'unscore'.
I don't understand the reason. |

It should be "

dataset, the length of the first evaluation of the
label will be applied to all labels."
However, if you use the proc format, their is no truncation problem now. |
