Re: Performing a do loop over a list of values. &VALUE is constant. &NEXTVALUE is what changes each time through the loop. Whatever it is you want to generate as a SAS program, it has to be inside the%DO loop, not outside. And it should refer to &NEXTVALUE instead of &VALUE.

On the first iteration of the loop if a%DO%WHILE condition is false, the code inside the loop will not be excecuted. But on the first iteration of a%DO%UNTIL loop if the condition is true, the inside of the loop will be executed.

can be any macro expression that resolvesto a logical value. The macro processor evaluates the expression at the topof each iteration. The expression is true if it is an integer other than zero.The expression is false if it has a value of zero. If the expression resolvesto a null value or to a value containing nonnumeric characters, the macroprocessor issues an error message.

These examples illustrate expressions for the %DO %WHILEstatement:

• %do %while(&a<&b);

• %do%while(%length(&name)>20);

The %DO %WHILE statement tests the conditionat the top of the loop. If the condition is false the first time the macroprocessor tests it, the %DO %WHILE loop does not iterate.

You can invoke the macro UNTAG as

Adobe flash plugin not working. Flash plugin not working. If Adobe's Flash Player Help page does not show that Flash is working even though you have installed the latest version, your Flash plugin may be disabled in the Add-ons Manager. To make sure that Flash is enabled.

The macro then generates this TITLE statement:

If the title text containedspecial characters such as commas, you could invoke it with the %NRSTR function.
