confusion with separators #20
Description
When inputting data in csv format, the EXNAME must not contain any "_" underscores. Dashes are OK.
Conversely, DOME INFO blocks must not contain any "-" dashes. Underscores are OK.
This is very confusing to remember and to teach others. But the translators are strict and mistakes cause errors, which are difficult to troubleshoot.
We need better diagnostics and error messages about these (and probably other) common input errors.
