It’s possible to insert the command below under keys in the Display Manager (DM) in SAS. The command will reset the line number in the log, clear the log and jump back to the editor.

Getting first megabytes of large file
You can use the DOS-command TYPE and MORE to get the first megabytes or gigabytes of a large file e.g. of TXT, XML, CSV etc.
This is done by piping the result into another file, there by getting only the first part of the file piped into the new file.
The DOS-command below will start piping the large file into the smaller new file.
|
1 |
type LARGE_SOURCE_FILE | more > SMALL_DESTINATION_FILE |
You are not able to see the result from the DOS-command. You need to press the SPACE-key on your keyboard, because every time you press the SPACE-key a new page of the file will be showed and thereby piped into the SMALL_DESTINATION_FILE.
When you think you have done this enough times, then you have to press CTRL-C on your keyboard, this will terminate the type-command and you will have the SMALL_DESTINATION_FILE containing data from the LARGE_SOURCE_FILE.
Be aware that you will get the — more — pipe text in the file!
SQL-statement to find lowest observation in dataset
The SAS SQL-statement below will create a dataset containing all information for the observation with the lowest age in the dataset SASHELP.CLASS.
|
1 2 3 4 5 6 7 8 |
proc sql; create table CLASS as select * from SASHELP.CLASS group by AGE having AGE=min(AGE) ; quit; |
The syntax for the SAS SQL-statement is showed below.
|
1 2 3 4 5 6 7 8 |
proc sql; create table <DESTINATION TABLE> as select * from <SOURCE TABLE> group by <COLUMN TO SEARCH> having <COLUMN TO SEARCH>=<FUNCTION>(<COLUMN TO SEARCH>) ; quit; |
As you see the <FUNCTION> doesn’t have to be min (minimum), it can be any function working on the type of <COLUMN TO SEARCH> – numeric or char.

Info about SAS-datasets in the WORK-library
In SAS Enterprise Guide it is not very easy to see the size and number of observations in datasets in the WORK-library.
The macro below looks in the DICTIONARY.TABLES and gets these info for the WORK-library. Be aware that it will not work for views, because it’s not doing and actual count of the SAS-datasets.

Microsoft Team Foundation Server (TFS) and SAS
Below is shown how you can extract the current Microsoft Team Foundation Server (TFS) revision number for a given file into SAS and use it in your SAS program.
Be aware that Visual Studio 13 is used in the example below. It is uncertain if newer versions of Visual Studio will work.

You can now use the three diffent macrovariables called tfsver1, tfsver2 and tfsver3 in your program.
Microsoft Visual Studio Team Foundation Server 2013 Power Tools might be needed.

Automatically analyzing and documenting SAS-code
In SAS Enterprise Guide and SAS-DI you have the possibility to analyze the code for a SAS-program.
The picture below shows the Analyze Program option in SAS Enterprise Guide.
Analyzing the code should result in a conversion of the SAS-code to a SAS Enterprise Guide flow or SAS-DI flow. But none of these code analyzers are very good. Depending on the complexity of the SAS-code you put into the analyzer, they will leave you with a more or less successful conversion. And more times than not they will fail at doing the job.
But SAS comes with a procedure PROC SCAPROC that does a really good job at analyzing and documenting SAS-code.
Below is an example.
|
1 2 3 4 5 6 7 |
proc scaproc; record '<PATH>' attr expandmacros; run; proc scaproc; write; run; |
The links below gives you further descriptions of PROC SCAPROC and its options. There’s also a guide on how to do a graphical presentation of the result fra PROC SCAPROC.

Testing a port with PowerShell
In newer versions of Windows you are not able to use the Telnet-command to test a port. Don’t worry. In PowerShell v. 4 and onwards you can use the command below.

Test-NetConnection <host> -port <port> |
Eg.
