Use string attributes, not ASCII
Posted on September 9th, 1997 by shacker
If you’re creating custom filetypes and and want to be able to edit their attributes in the Tracker, be sure to establish them with a datatype of „String.“ Don’t be tempted to use the „ASCII“ datatype.
If you do, you won’t be able to edit them even if you’ve set the „editable“ flag. The ASCII datatype is being deprecated and will not be present in future versions of BeOS.
