Close Data File

Controls: File Menu >> Close
Macro: Close

You can close a previously-opened data file from this File menu option, or you can simply toggle off the DD / Open button in the toolbar.

You only need to explicitly close a data file if you want to return to live Input or Generator operation. If you just want to view a series of files, simply opening the next one will cause the prior one to be closed automatically.

If you have changed the Notes or User Units calibration for the file, when you attempt to close it (or open another, or when you attempt to exit Daqarta) you will be reminded of this and prompted to save it.

However, only .DQA files can hold Notes and calibration information, so be sure to save single-screen files in that format if you want to preserve these.

If you are prompted to re-save long DDisk (.DQA or .WAV) files, there is no format option... they are always saved in .DQA format. Even if the file has a .WAV extension, it will really be a .DQA file in order to include the extra information. Such files can still be read by other software that follows the standard rules for reading .WAV files, which require ignoring any information they can't handle properly. (Long .DAT files can not be re-saved.)

Macro Notes:

Close= (no parameter needed) will close any open data file. If there is no file open, the command is ignored.

This is useful in macros that are, for example, about to toggle Generator or Input on, since those are disabled when a file is open and would provoke a "Control disabled. Aborting macro" error.
