I've spent this week describing the functionality and purpose of the MCOVERAGE system option introduced in SAS V9.3. Coverage testing is an important consideration for your testing strategy - it's important to know how much of your code has been tested...

Over the last few days I've been revealing the features and benefits of the MCOVERAGE system option introduced in SAS V9.3. This system option creates a log file to show which lines of our macro(s) were executed, e.g. during our tests.Knowing that we t...

Over the last couple of days I've been uncovering the MCOVERAGE system option for coverage of testing of macro code. Coverage testing shows which lines were executed by your tests (and which were not). Clearly, knowing the percentage of code lines that...

Yesterday I introduced the MCOVERAGE system option (introduced in V9.3) for capturing coverage of macro execution. This is useful in testing, to be sure you executed all lines of your macro. This may take more than one execution of your macro, with different input parameters and data.
I finished yesterday's post by showing the...

The SAS macro language is almost as old as SAS itself (who knows exactly?) so you'd think the need to add new functionality would have ceased - particularly with the ability to access most DATA step functions through %sysexec. But apparently not...SAS ...

I use relatively fixed patterns in my SAS programming life. For so called data driven programming (or dynamic programming), I used the following 4 techniques, chronologically: macro array call execute list processing for each loop For a quick demo, I will start with a simple scenario in which the data set sashelp.zipcode should be...

Suppose you have 10 datasets, literally ds1, ds2, …ds10 and you need to concatenate them all. You may first get a quick shortcut set ds1-ds10. If such list members were generated dynamically (and may hold a form like ds1a, ds2a,… ds10a) , you will probably come out a macro solution: %macro doit; ...
