[great-users] cut operator

[Aditya Agrawal]

Dear Tivadar,

In GReAT the test case has a default semantics that is the equivalent of a 
set of if blocks

if(Case1) 
{
}

if(Case2)
{
}

....


The cut operator in an earlier if statement makes the rest become else ifs

Thus, if I have 3 cases 1, 2, and 3 and the second one has a cut, the 
equivalent pseudo code will be as follows:

if(Case1)
{
}

if(Case2)
{
}
else
{
       if(Case3)
       {
       }
{


The effect you are wanting to get is a different thing and the cut wont 
help you there. What you need is to change the attribute "For All" in the 
case from true to false. This attribute tells the matcher weather to look 
for all the matches or the first match.

Thanks,
Adi
