Can't load a .mat file due to infinite while loop

I want to load in a .mat file into my program using the load function however I have an infinite while loop causing the file to not load unless there is a break. Is there anyway to fix this? Is there an easy replacement for my infinite loop? Thanks for any suggestions.

X and Y are motors

looprepeat = true;

x.MoveHome(0,0);
y.MoveHome(0,0);
pause(15);

load('locations.mat');

while looprepeat %Allows for user to move to row and column infinite time 
    row = input('Please enter in row number: ');
    column = input('Please enter in column number: ');
    y.MoveAbsolute(0,posy)
    x.MoveAbsolute(0,posx)
    pause(15);
    for g = 1:row
        y.MoveJog(0,1);
        pause(3);
    end

      for k = 1:column
          x.MoveJog(0,1);
          pause(3);
      end

end

The file has already been loaded before you enter the loop; Matlab is sequential in operation. Are pos[x|y] supposed to be coming from there, mayhaps? If so, are they vectors and is there a problem w/ the method handling that with an absolute move?

Not enough info to really be able to say much...as for the loop what's to fix and what's the desired result to be?
