Subject:      %IF usage to compare Strings
Content-Type: text/plain; charset=iso-8859-1

Hi Guys,
  Question1
  I am having problems with comparing Strings using %if in a macro setting.
  For example : I know that CommandString = Slope ;
  But I want the Value of the macro variable : i.e.
  CommandString = Slope ; Level ;
  whenever CommandString = Slope ;
  I use the following code:-
  %if &CommandString=slope %str(;) %Then %CommandString=level%Str(;)slope%str(;);
  But unfortunately, the above code returns False even though its True.

  Question2
  Is there a way to break out of a loop in Macro? Inother words if a loop in the macro returns an error, it keeps repeatingt till the program crashes....in other words is there a way I can break oout of the loop dynamicaly and resume it with a new dataset?

  Your help is highly appreciated.
  Many Thanks !!
