Hello,   I have a reference code and I want to remove hash table out of it since I'm new to SAS and it is adding a lot of complication and errors when I run the code with it. Here is a sample of what I'm doing:   assuming dataset ‘ds1’ looks like the following: phoneno accno amt custno dda 1234567601 10234567601 10 65463 454646328 1234567602 21234567601 2000 545 8769646328 1234567603 32234567601 456856 5345 87634646328 1234567604 43234567601 5858 34545 3469646328 1234567605 54234567601 56567 34 99646328 1234567606 65234567601 575 32 79769646328 1234567607 76234567601 45 324646 239646328 1234567608 87234567601 45 121 6789646328 1234567609 98234567601 45 432 87696463458 1234567610 99234567601 452332 13421 9869646328   My code:   data ds2; if _n_=1 then do; dcl hash hh (dataset: 'ds1'); hh.definekey ('phoneno'); hh.definedone(); end; keep address zip phoneno dda tdda; %INCLUDE INCLF(f1.sas);  //code for f1 provided below                                                                                                        if hh.find()=0;                                                                                                                  %INCLUDE INCLF(f2.sas); //code for f2 provided below                                                                                                       Run;   F1 code: Attrib FILEDATE; –this is a variable in ds3 Set ds3 end=eof;   IF CUBL > 000  –this is a variable in ds3      AND DDA NOT IN ('28378','657479') ;                                                   Keep _All_ ;           F2 code: Length TDDA $ 1;                                                              If DDA in (‘99646328’ ‘9964632823)Then                                                                      TDDA = 'Y';                                                                  Else                                                                              TDDA = 'N';     ...

I have a dataset created 'abc' in a sasgrid location I'm creating another dataset 'xyz' through that using hash table, for eg.,   data xyz; if _n_=1 then do; dcl hash hh (dataset: 'abc'); hh.definekey ('phoneno'); hh.definedone(); end; followed by a bunch of keep statements run;   when I try and run this, I get the following 2 errors: ERROR: Undeclared key symbol phoneno for hash object ERROR: DATA STEP Component Object failure. Aborted during the EXECUTION phase.   what does this even mean? what do I need to change to sort this? sorry I'm very new to hash tables ... View more
