urlread retrieves data but webread retrieves error
Show older comments
I'd like to retrieve data from a .csv generated by a website. urlread works, but is not recommended. webread returns a http error message. Anyone know what feature of webread causes different behavior than urlread? Alternatively, is there a script to just download the file (e.g. web.m but without the interactive browser)?

I have the same issue.
How is this an "Accepted Answer"? If I understand the fix is to manully edit the file to change the delimiters by hand?
Can webread delimiter be user settable? If not will urlread stay put until it does?
url = 'https://ssd.jpl.nasa.gov/sbdb_query.cgi?com_orbit_class=JFC;table_format=CSV;c_fields=AbAc;&query=1'
url_amp = regexprep(url, ';', '&')
char(webread(url_amp).')
