1. SAS macro to Create / Remove a PC Directory... Here's a SAS macro to Create and Remove a PC Directory... Often we ignore Notes and warning in the SAS log when we try to create/remove a directory that does/doesn't exist...This macro first checks for the existence of the directory and then create/delete it or else put a message to the SAS log...try it out :-) /* Macro to Create a directory */ %macro CheckandCreateDir(dir); options noxwait; %local rc fileref ; %let rc = %sysfunc(filename(fileref,&dir)) ; %if %sysfunc(fexist(&fileref)) %then %put The directory
&dir
already exists ; %else %do ; %sysexec mkdir
&dir
; %if &sysrc eq 0 %then %put The directory &dir has been created. ; Read more @ http://sastechies.blogspot.com/2009/11/sas-macro-to-remove-pc-directory.html Ways to Count the Number of Obs in a dataset and pass it into a macro variable... Well...there are many ways of getting the observation count into a macro variable...but there a few pros and cons in those methods...1. using sql with count(*).. eg. proc sql; select count(*) into :macvar from dsn; quit; pros: simple to understand and develop cons: you need to read the dataset in its entirety which requires processing power here...2. datastep eg. data new; set old nobs=num; call symputx('macvar',num); run; Read more @ http://sastechies.blogspot.com/2009/11/ways-to-count-number-of-obs-in-dataset.html SAS macro to split dataset by the number of Observations specified Suppose there was a large dataset....This SAS macro program splits the dataset by the number of observations mentioned...macro name%split(DatasetName, No ofobservation to split by)/* creating a dataset with 100000 observations*/ data dsn; do i=1 to 100000; output; end; run; %macro split(dsn,splitby); data _null_; set &dsn nobs=num; Read more @ http://sastechies.blogspot.com/2009/11/sas-macro-to-split-dataset-by-number-of.html SAS macro to reorder dataset variables in alphabetic order... How do you reorder variables in a dataset...I get this many a times.... Here's a macro for you to achieve it...For example I've used a dataset sashelp.flags and created some more variables with variety of variables with names upper / lower cases and _'s to demonstrate the reorder macro.... Please try this macro for yourself and let me know your suggestions.... /* Example dataset with variety of variable names */ data flags; set sashelp.flags; a=2; b=4; Read more @ http://sastechies.blogspot.com/2009/11/sas-macro-to-reorder-dataset-variables.html Use SAS function Propcase() to streamline Google Contacts You might think I am crazy...but I have been using this macro for a long time to fix some contacts in my Google Contacts...I get a little irritated when I can't find a particular person by email...so I wrote this macro...This macro takes for Input a .csv file that is exported from Google Contacts and outputs a file that is ready to be imported to Google Contacts....often I wanted to have Names in the proper case...Try it yourself and let me know if it needs any tweaks...Propcase in SAS Documentation. %macro organizeGoogleContacts(infile,outfile); /*Import your contacts into SAS */ data googlegroups; infile

For eg, a dataset has 400 fields and 20,000 records. If we can split the dataset into two, with 200 fields and 20,000 records in each dataset with a common field like loan number as primary key would be helpful to load the details for analysis. /** To be called like this... %splitdsnverticallykey(dsn,varperdsn,keyvars=); eg. %splitdsnverticallykey(sashelp.vtable,4,keyvars=memname libname); Where ----------- dsn - libname.datasetname to be split varperdsn - How many vars per dsn excluding the key variables keyvars - specify the primary key variables */ Read more @ http://sastechies.blogspot.com/2009/11/sas-macro-to-split-dataset-into.html SAS Macro that reads the filenames available at a particular directory on any FTP server (i.e. Windows Network Drive/Unix/Mainframe) Here's a macro that reads the filenames available at a particular directory on any FTP server (i.e. Windows Network Drive/Unix/Mainframe)... For Windows network drives we use the Filename Pipe Statement For Mainframe and Unix we use the FileName FTP protocol statement.
