SET with POINT= option with STOP statement Direct access by record number Temporary, effective SAS Indexes Direct access by key variable value for more effective ascending sorting/merging and subsetting Permanent, up to 50% faster with PROC SORT if merging datasets, up to 100% slower without PRO...
The final merge statement will be a bit messy if there is an easier way to do this it would be helpful. But I will no longer need the merge a and b statement - this was causing a warning, which I think it was because of the multiple observations with the same VAR2 i...
LIBNAME statement the following options are new: COMPRESS= controls the compression of observations in output SAS data sets in a SAS data library. CVPBYTES= specifies the number of bytes to use in order to expand character variable lengths when processing a SAS data set that requires transcoding....

if there is any possible duplicate, we can use the SPEDIS function in the SQL statement to look up any pair of the records. Here we set the argument to be 25 in order to detect any singlet. ***(5SPEDIS/SOUNDEX: fuzz matching***; ***(5.1)SPEDIS: find spellingmistakes***; proc...
with libref and assign the statement which remains assigned to change the SAS session. It will mainly follow the same rules, like four types of rules, not more than the eight characters required; the first set of characters should be the letter, followed by the subsequent set of characters ...
It reorders the values for specified data like input and output datasets with valid names like sorted order containing multiple duplicates. The data observations are performed on each set of rows and columns, identifying the unique records set in the user input dataset. ...

We can use theCHANGE old-dataset-name = new-dataset-namestatement in the PROC DATASETS procedure to rename a SAS dataset. In the code below, we are renaming "cars" dataset to "automobiles". data cars; set sashelp.cars; run; proc datasets lib=work nolist;change cars = automobiles;quit;...
