The code runs fine but only for the intial and second time through. Do you have any idea why this may be?? Code i inserted to run loop follows:

L=128
f100='C:\MATLAB701\work\Points_CloudsL1';
for idx =1 : 10
if idx==1
%load the spreadsheet
flin='C:\Documents and Settings\prhill\My Documents\Hill\Point_Clouds\20_1_00.asc';
flout=[f100,num2str(101)];
else
flin=flout
flout=[f100,num2str(100+idx)];
end

points=load(flin);
