Hi Bob,
What about this:
fid1 = fopen('file1.txt');
fid2 = fopen('file2.txt','w');
tline = fgets(fid1);
Character2add = 'xx_'; % here put the character to be added
while ischar(tline)
disp(tline)
fprintf(fid2,'%s %s\n',Character2add,tline);
tline = fgets(fid1);
end
fclose(fid1);
fclose(fid2);
Regards
