I have a short code that I have put a debug marker in, before running it, but when it gets run the code moves past the marker and stops on an error. There isn't any logic that should cause it to skip over (I can move the marker seemingly anywhere in the code before the error and it still gets skipped.)
Anybody have any suggestions?
The code looks something like the following:
for ii=200:200:30000
command=['!systemcommand outfile.dat.' num2str(ii) ' 9.0932 0.0000 1.8288 > File.out'];
for jj=1:200
linep=fgetl(fid); % Crashes here.
if length(linep) >=2
if strcmp(linep(1:5),'T ')
elseif strcmp(linep(1:6),'taubeg')

@Bob Thompson: Avoiding EVAL is a good programming practize, not only in MATLAB, but as well in other interpreted langauges. MATLAB's code analysis cannot estimate the side effects of an EVAL command and therefore this command can have side-effects on the JIT acceleration although no variables have been defined dynamically.

Are you sure the file is saved before you try to set the breakpoint? I notice that if you stop at a break point, edit the code, and then try to set another breakpoint, it won't let you. And you can't save it while it's running or stopped at a breakpoint. You have to stop running completely, then save it, then set your breakpoint.

Thanks, I'll look into that.
