set several data set together with cut off variable

Ivy — Wed, 03 Feb 2016 21:32:02 GMT

Dear all,

I tried to combine several data together by using set statement.

Thought I ues length statement to set up the "var_level " as $ 100 . However , the var_level was still trucated.

Any solution ? Thank you very much ! (The length is enough to cover the var_level at each file. , no error message. )

Ivy

data rpt_cat;
length var_level $ 100. ;
set rpt_gender

rpt_uidxinsplan ;
run;

3218 data rpt_cat;
3219 length var_level $ 100. ;
3220 set rpt_gender rpt_uidxinsplan ;
3221 run;

NOTE: There were 3 observations read from the data set WORK.RPT_GENDER.
NOTE: There were 14 observations read from the data set WORK.RPT_UIDXINSPLAN.
NOTE: The data set WORK.RPT_CAT has 17 observations and 7 variables.
NOTE: DATA statement used (Total process time):
real time 0.01 seconds
cpu time 0.00 seconds

Please post code used.

Make sure you put length statement before the SET statement.

Most likely, the variable also has a format attached to it that is truncating the displayed value. Add the FORMAT statement AFTER the SET statement, to remove the format:

format var_level;

Good luck.

Edit: I see, @Astounding was faster and had the same idea.

Hello @Ivy,

The reason for the truncation may be a format (such as $17.) which is permanently associated with variable VAR_LEVEL. This would be shown in column "Format" of the PROC CONTENTS output for dataset RPT_CAT. You could get rid of this format by adding the following statement before the run; in your data step:

format var_level;

Thank you very much ,

Removing format works beautifully !
