How do I continue to read files in a loop when an error occurs?

Hello, I am trying to read .FIT files provided by my teacher and when reading the last bunch of them an error occurs. I tried using a try catch to continue, and it skips over and continues the loop, but I am not getting my value D.
Error using fitsinfo>openFile (line 760)
Unable to open file. File might be corrupt or filename might have unsupported characters.
for l = 100:999
try
fit2file = sprintf('x.000000%d.FIT',l);
D = fitsread(fit2file);
catch
end
end
Thank you in advance

Try reading the file that causes the error to check if it's corrupted. If It's not, consider renaming your files, 'x.00001.FIT' could be prone to failures.

your loop overwrites D with the last file content it was able to read, but does not define D if no files could be read.
