Usage Note 24439: In SAS 9.1, are there easier ways to customize page numbers in RTF output? direct link here http://support.sas.com/kb/24/439.html Yes, beginning with SAS 9.1, page numbers can be customized in the RTF destination by using an escape character and the {thispage} function, {lastpage} function, {pageof} function, or all three: ods escapechar=' ^ '; ods listing close; ods rtf file=' c:\tests\test.rtf '; data test ; do i= 1 to 50 ; output; end; run ; proc print data=test noobs; title ' Page ^{thispage} of ^{lastpage} '; footnote ' ^{pageof} '; run ; ods listing; ods rtf close;

How to calculate number of years and number of days between 2 dates; Exploring the yrdif and datdif functions in SAS as well as INTCK function: There are several ways to calculate the number of years between two dates and out of all the methods, YRDIF function results the most accurate value. Syntax: ageinyrs = YRDIF(birthdate, enddate, ' act/act '); ag_indays = DATDIF(birthdate, enddate, ' act/act '); “ act/act ” will gives us the actual interval between the two dates. The YRDIF function returns the calculated years between two SAS date values. The returned value will be a precise calculation, including multiple decimal places. Whereas with INTCK function will just give the rounded value like 10, 11 and not like 10.2 and 11.5. Syntax: Using YRDIF function: To know the interval between two dates in Years: data _null_; sdate=" 12mar1998 "d; edate=" 12jun2008 "d; years=yrdif(sdate,edate, 'act/act' ); put years ; run ; ...

IN SAS programming, we often require outputting the dataset in different formats like EXCEL and CSV etc and here are the five different ways to export the SAS dataset into .csv file. Example: data new ; infile datalines dsd dlm=' ' missover; input a b c d; datalines; 3 5 1 1 4 1 . . 5 8 3 2 6 0 4 4 ; run ; By putting MISSOVER in the infile statement we are telling SAS to do not look for the data in the next lane if it runs out of the data, instead keep missing values for any remaining variables. DSD and DLM options should be included always in the infile statement, if we include the dlm=’ ‘ in the infile statement then SAS will put one digit for each variable even though we haven’t assigned any length to variable. DSD option will tell SAS to consider a missing value if 2 delimiters are present side by side in any observation. When we ran the above program in SAS, we create a SAS dataset name ‘ NEW’ in the work directory and if we want to create a ...

Reading from Excel Spreadsheets: Microsoft Excel spreadsheets can be read from SAS in several ways. Two of these will be demonstrated here. First, PROC IMPORT allows direct access to Excel files through SAS/Access to PC File Formats or access to Comma-Separated (CSV) files through Base SAS. The second method uses the Excel LIBNAME engine. PROC IMPORT The IMPORT procedure reads from external sources and creates a SAS data set. Two sources are Excel spreadsheets and CSV files. A particular SAS/Access product may be required for certain sources, however. In our example, SAS/Access to PC File Formats is required to read an Excel file, but a CSV file can be accessed with Base SAS. General Syntax for PROC IMPORT: PROC IMPORT DATAFILE=" c:\sas\ego.csv " OUT=jeeshim.egov DBMS=CSV REPLACE; For Excel you use the DATAFILE =”filename” option to specify the Excel file to be read. (The TABLE=”tablename” option would be applicable if you were reading from a database such as Microso...

The following excerpt is from SAS OnlineDoc documentation: ? or ?? Direct link: http://www.nesug.org/Proceedings/nesug01/at/at1013.pdf The optional question mark (?) and double question mark (??) format modifiers suppress the printing of both the error messages and the input lines when invalid data values are read. The ? modifier suppresses the invalid data message. The ?? modifier also suppresses the invalid data message and, in addition, prevents the automatic variable _ERROR_ from being set to 1 when invalid data are read. Below is an example of using ?? to determine whether a variable contains non-numeric values or not: data _null_; x = “ 12345678 ”; if (input (x, ?? 8. ) eq . ) then put ‘ non-numeric’ ; else put ‘numeric’ ; run ; Running SAS would return “Numeric” in the above example. If we used X=”123a5678”, SAS would return “Non-Numeric”. Note that the input format in the above example is “8.” So only the first 8 bytes of the character string are checked...

Proc SQL: Power of SAS SQL: • SQL looks at datasets differently from SAS – SAS looks at a dataset one record at a time, using an implied loop that moves from the first record to the last – SQL looks at all the records, as a single object • Because of this difference SQL can easily do few things that are more difficult to do in SAS • There are a number of built in functions in SQL that can be used in a select statement • Because of how SQL handles a dataset, these functions work over the entire dataset • Functions: – Count: Counts Values – Sum: Sums Values – Max: Identifies the largest value – Min: Identifies the smallest value – Mean: Averages the values Read more at www.cognigencorp.com/perspective/tipsNtricks.pub/1/PROC%20SQL%20Talk_12_.ppt – SAS SQL Introduction to Proc SQL AN INTRODUCTION TO PROC SQL® PROC SQL: When and How to Use It?

Q&A: numeric variables length more than 8? We all know that the default length of the numeric variables in SAS is 8 and if suppose I want to store a number lets say (12345678910, which has a length 11 to numeric variable) to variable total, what should I do? What if the numeric variable digits are more than 12 digits and i want to store them all without any E values? ANS) The default length of numeric variables in SAS is 8 and all the numbers that we see in the sas datasets are called as floating numbers(floating point binary) and not a regular sequence numbers form 1 to 10. When we are using SAS/Windows as our operating system and then the minimum length for any numeric variable should be 3(not 1 as we get confused all the time). So if a variable contas less than 3 digits means it is stored with less space. The reason is, since a numeric variable will need a power and and the sign(+ or -), if SAS want to store a numberit defenitely needs a minimum of 3 bytes. Depending ...
