xcall SETDFN([file_spec][, option])

Arguments

file_spec

(optional) A field, literal, or record that contains the filename path and extension to be used as the new default by the runtime. (a)

option

(optional) Flag to indicate where file_spec will be applied: (n)

0 = The non-ISAM default path and extension (default)

1 = The ISAM default path and extension

2 = Both the ISAM and non-ISAM default path and extensions

Discussion

The SETDFN subroutine sets the default filename path and extension to be used by the runtime.

If file_spec is missing or null, the original default filename path and extension is restored.

Setting the default path and extension only works on your local machine. xfServer always uses the default path and extension.

On OpenVMS, the initial default filename specifications used by the runtime library are SYS$DISK:[ ].DDF for non-ISAM operations and SYS$DISK:[ ].ISM for ISAM operations.
