Be careful.You cannot create a macro variable with CALL SYMPUT and use it in the same DATA step.Here’s why. When you submit macro code, it isresolvedby the macro processor, and thencompiledandexecuted.Not until the final stage— execution—does SAS see your data.CALL SYMPUT takes a data...

because a macro is not allowed to create a macro variable %* in a local scope above its own. %* (It may however, access any macro variables in scope above itself) %* If this macro implicitly 'creates' a macro variable, it will %* be destroyed when the macro ends, and thus will n...
There is a function to check if a macro variable exists. %put %symexist(TEST); If the underlying problem is caused by using the INTO clause of PROC SQL to populate the macro variable then set the default value before the query that you are using to set it. %let test=0; select count...

These variables are macro variables that have been defined either by SAS or by you. A collection of application/vnd.sas.compute.variable items is returned.

To cater for this scenario, it is possible to export the variable types (and other attributes such as label and format) by adding a showmeta param to the webout() macro as follows: %webout(OBJ,a,missing=STRING,showmeta=YES) The %webout() macro itself is just a wrapper for the mp...
