A file can have multiple bits set like 3 (hidden + read only). So you can clear multiple bits by combining the bits.
When you specify the filename, make sure it does not have a wildcard. CLEARTTR does not support wildcards.
When you omit the filename, the last found file from DIR() will be used for the operation.
In VB, CLEARATTR expects a new value for the attribute which replaces the old attribute byte.
In AVR-DOS you specify the bits to clear. So old attribute bits which are not altered are kept.
In AVR-DOS you can also set the individual bits using the SETRATTR statement.
