in thread Grep question

I will post the more code to give you guys a better idea of what I am trying to accomplish. I have no problem getting this to work, but I have been cleaning it up a bit. Originally it was about 40 lines, and now I have it down to this. In the process I am learning about perl Data structures.

###---  Define options for select Status ---###

@statusoption = ('Waiting Approval' , 'Denied' , 'Approved' , 'Ordered
+' , 'Building' , 'Built' , 'Shipped');

if ($purchase eq "Already Have") {
  delete @statusoption[3];
} 
if ($purchase eq "Virtual Machine") {
  delete @statusoption[3];
  delete $statusoption[6];
} 

@statusoption = grep {$found++ if $_ eq $status; $found } @statusoptio
+n;

    Actually the code is as follows
    ###---  Define options for select Status ---###

@statusoption = ('Waiting Approval' , 'Denied' , 'Approved' , 'Ordered
+' , 'Building' , 'Built' , 'Shipped');

if ($purchase eq "Already Have") {
  delete $statusoption[3];
} 
if ($purchase eq "Virtual Machine") {
  delete $statusoption[3];
  delete $statusoption[6];
} 

@statusoption = grep {$found++ if $_ eq $status; $found } @statusoptio
+n;
