Macro Load File

Controls: Options >> Macro Dialog >> Load File

This allows you to load a collection of Daqarta macros that was previously Saved as a .MAC file. If present, Daqarta0.MAC is loaded automatically at start-up. This button allows you to load a different macro set at any time. For example, you may want to keep different macro sets for entirely different tasks.

Alternatively, you may load other DaqartaN.MAC files at startup, where N is any alphanumeric character, by invoking Daqarta using the M:N parameter. You can create separate desktop icons that load different macro sets for different purposes.

Assuming you have a desktop icon from a standard Daqarta installation, first create a copy by right-clicking and selecting Create Shortcut.

After the new icon appears on your desktop, right-click it and select Properties. Under the Shortcut tab, the Target line will show something like:

"C:\Program Files\Daqarta\Daqarta.exe"

Add the M: parameter at the end of that line (outside of the quotes). For example, to load Daqarta1.MAC you would change the above to:

"C:\Program Files\Daqarta\Daqarta.exe" M:1
