These are symput and symget. The syntax used is CALL SYMPUT argument1, argument2where argument1 is the macro variable that we are creating which will store the value that is being passed out of the data step and argument2 is the value in string format. Notice that the new macro variable has to be in single quotes.
Furthermore, you might have parameters values that are contained in a SAS data set because they were computed by a previous program. A few procedures support reading parameters directly from a SAS data set, but most require that you type the values manually.
This is a common question that SAS programmers ask on discussion forums. This article shows how you can read the values of a variable from a data set into a SAS macro variable. The macro variable will contain a blank-delimited list of values.
You can then use the "macro list" to specify the parameters to a SAS procedure. Usually the delimiter is a blank character, as below, but in some situations you might want to use a comma.
It converts them to character values and concatenates them into a blank-separated string, which is then stored into the macro variable named ParamList.
To create a macro variable, use ideas from the articles about concatenating a vector of values into to a string and about using the SYMPUTX subroutine. Create a macro variable with the specified name.
By default, the module creates a blank-delimited list, but you can override that default.
After the call, you can then use the macro variable in other SAS procedures. However, when you do need a macro variable, this technique is worth remembering.Writing cleaner and more powerful SAS code using macros Patrick Breheny.
complex, and generalizable SAS programs • Macros can greatly reduce the effort required to read and write SAS Code. Outline 1. Macro Basics 2. Working with Macro Strings 3. Getting More Out of Macros: • A period is the signal in SAS to end a macro variable name.
Read the values of a variable into a SAS macro variable. You can use the "macro list" to specify a list of parameters to a SAS procedure. Fortunately SAS also provides options for those, EOV allows us to identify the first record in a file and FILENAME allows us to identify the file name of the file imported.
Enough talking, here's what the full code would look like. Writing vba code in sas.
Ask Question. up vote 2 down vote favorite. I want to implement my VBA code into my SAS-code, so I can do the whole process with one run.
You're saying that you want to be able to create a new Excel file via DDE and then create a new VBA macro in it programatically via SAS? – Joe Jun 26 '15 at Basically, Yes. Nine Steps to Get Started using SAS You can write a macro definition to execute code conditionally in nine steps.
The macro definition developed in this tutorial prints hotel information from a SAS data set named EXPENSES that is updated with resorts' costs and amenities as they change. You. Generating SAS Code Using Macros. Macros allow you to substitute text in a program and to do many other things. A SAS program can contain any number of macros, and you can invoke a macro any number of times in a single program.
