How Can I Find a Time Format that Does Not Remove the Leading Zero e.g. Time5 (output printed as 09:36 instead of 9:36)? I have found an intersting solution to this problem in http://www.sas.com/ ; direct link (Suggested by Stephen Hoar, Lloyds TSB) There is currently no time format that puts leading zeros automatically in time values. But there are a number of ways of achieving this, below are some examples. Example 1: Create your own custom format using the following syntax. Then format your data values using the user defined format. proc format ; picture military other = '%0H:%0M:%0S' ( datatype =time) ; run ; data test; x= ' 9:36't ; format x military8. ; put x=; run ; x=09:36:00 Example 2: You can also use the TODw.d format which does write leading zeros, but the original value must be a SAS datetime value. To convert your time values to datetime values use the DHMS function. In the DHMS function insert the value: 0 date, 0 hours, 0 minutes, and then...

There is a set of SAS macros, converts a directory of transport files to a directory of SAS data sets and format catalogs (and vice versa). To see how to invoke the macros, look at the test following the last macro. The macros make the assumption that transport files created from data sets have the extension .xpt, and transport files created from format catalogs have the extension .xpf. %expfmts : This macro will convert an existing format catalog into a data set in transport format. % expdset : This macro will convert an existing SAS data set into a transport file. %impfmts : This macro will convert a transport CNTLOUT data set into a native format catalog. %impdset : This macro will convert a transport data set into a native SAS data set. %getnames : This macro will create a SAS data set consisting of a variable called FILENAME. There will be one observation for each file in the specified directory with the specified extension. Direct link: http://www.sas.co...

In my view, Display Manager commands didn’t get much attention of SAS programmers as they should be. It may be because... 1) SAS Documentation has very little information about how to use this facility. 2) Even Google searches aren’t helpful enough. Here is the list of Display Manager Commands I know… dm "log; clear; out; clear;" ; *Clears Output and Log Window; dm " vt work.dsn" ; *Opens the dataset DSN in a View table window; dm "vt &syslast" ; *Opens the dataset recently created; dm 'next viewtable:work.dsn; end; ' ; *Closes the VT window of DSN; dm 'keydef f12 submit' ; *Assigns the submit command to the F12 key ; *Assigns clear log and output commands to F2 Key; dm "keydef F2 'cle log; cle output; submit'" ; *applies detail view to explorer window; dm   "next explorer; detail" ; dm "next log; detail" ; *Opens the Log Window; dm "next output; detail" ; *Open...

Yesterday I came across a website BLINK7. It is a great site to browse and to get help to improve your SAS knowledge in Proc SQL and Base SAS. This website offers a lot of information in the form of sample codes and tutorials on different topics in SAS. SQL for SAS Programmers - Introduction What is SQL? SQL stands for Structured Query Language and was designed for development and maintenance within a Database Management System (DBMS). A DBMS consists of one or more tables of data, typically joined in a hierarchical fashion, and a series of programs for organizing the data. Typical tasks performed with SQL code include the following: Retrieve (or query) data from one or more data tables Manipulate data within existing tables Define new tables and create data within new table Alter existing table definitions Set permissions for different users to access existing tables The first part of this tutorial deals with using the PROC SQL statement to perform basic data extraction.

Using the SAS Output Delivery System (ODS), you can create, customise, and manage HTML output in any operating environment by submitting programming statements. After creating HTML files, you can view them using Internet Explorer, Netscape Navigator, or any Web browser that fully supports HTML 3.2. ODS gives you new formatting options and makes procedure output much more flexible. With ODS, you can easily create HTML, RTF, PCL, PS, XML, Latex and PDF output, an output data set of procedure results and traditional SAS listing output. Also, ODS stores your output in its component parts (data and table definition) so that numerical data retains its full precision. Procedure output is divided into components, or output objects. Depending on the procedure that you run you might have one or several output objects created. For example proc print would create just one output object but proc univariate would produce multiple output objects. ODS stores a link to each output object in the results...
