Programming with SpartaDOS X

XIO 49, #IOCB,aux1,aux2,"Dd:fname.ext"
 

This is used to modify the attributes of a file or files. Wildcards are allowed in fname.ext. Aux1 is used to select which attributes are to be changed and whether they will be set or cleared. Aux2 is used to determine which files are to be affected.

To perform the desired attribute modification, add the following values to aux1, assuming an initial value of zero:

Protect	add 1	Unprotect	add 16
Hide	add 2	Unhide	add 32
Set archive	add 4	Clear archive	add 64

Aux2 is used exactly as with the scan mode of the open statement. It will select the files to be affected by current attribute status. These values should be added to aux2, starting with a base value of 0:

Protected	add 1	Unprotected	add 16
Hidden	add 2	Not hidden	add 32
Archived	add 4	Not archived	add 64
Subdirectory	add 8	Not a subdirectory	add 128

For example, to hide all of the files on drive #1 with a .BAK extender, use

    XIO 49,#1,2,0,"D1:*.BAK"

To protect and set the archive bit for all of the hidden files on drive #1, use

    XIO 49,#1,1+4,2,"D1:*.*"

and to unhide and unprotect all the hidden files with a *.BAK extender on drive #1, use

    XIO 49,#1,16+32,2,"D1:*.BAK"

The IOCB should be closed for this operation.
