I am running this code and it keeps warning me that the variable StateCd has multiple lengths specified. The variable must be named StateCd, so how can I fix this? I have attached my code below.

Thank you

 

 

 

DATA HypTabs.States (LABEL = 'Study States');
ATTRIB StateNum LABEL = 'State Number' LENGTH = 8
StateCd LABEL = 'State Code' LENGTH = $2
StateNm LABEL = 'State Name' LENGTH = $20;
SET HypImpt.States;
BY StateNum;
RUN;

PROC CONTENTS DATA = HypTabs.States VARNUM;
RUN;
PROC PRINT DATA = HypTabs.States;
RUN;

You define a length for StateCD but this variable already exists in your source data set with a different length.

If you really want to change the length then you will have to create a new variable with the same name.

data ds1;
  length stateCd $4;
  stateCd='ABCD';
  output;
  stop;
run;

data ds2;
  length stateCD $2;
  set ds1(rename=(stateCD=_stateCD));
  stateCD=_stateCD;
  drop _stateCD;
run;

Be aware that like in the code above if the new variable has a shorter length than the string from your source variable, the string might get truncated.

Before changing anything, examine StateCd in your original data. Verify that all.the values are no more than 2 characters long.

If that's the case, it is OK to run your program and ignore the warning.
