I have written a code in matlab with dialog box to open an input data file using diretorio = uigetdir; filename = uigetfile('*.txt','Select the INPUT DATA FILE');,
I do some process and produce the output using
prompt=('OUTPUT FILE NAME with .xls ext: '); title3='Output file name';
I have to run the same program for different input data files. Every time i run the program I feed the input file and get the ouput. Actually after the input data file is processed and the output file is created, the program should go to diretorio = uigetdir; for selecting another input file for processing / selection. Since there is no goto option in matlab, how to solve this. Can anyone help. Thanks in advance. Mohan.

Several options depending on what you want/need...
a) if you're processing all the *.txt files in a subdirectory, there's no reason to have to select each manually -- use something like
for ix=1:length(d)
... do processing here, save results w/ dynamic output file name...
b) if you aren't doing all but know which ones, use uigetfile() but use the multipleselection optional input option --
fn=uigetfile('*.txt','Select the INPUT DATA FILE(s)','MultiSelect','on');
Then use a loop like above except the filenames are in the cell string array instead of a structure
c) if you really do need to select manually each time, just wrap your code in a while() loop and continue as long as there is a valid selection each time through...
flg=true; % set the logic variable to start the loop
while flg
fn=uigetfile('*.txt','Select the INPUT DATA FILE(s)','MultiSelect','on');
if isequal(filename,0), flg=0; break; end % no file selected; quit
% otherwise process as above here
