4.7 Wait For Script – Status File Format
While FDT is in Wait For Script mode, a remote user may wish to find out what state the application is
currently in. This is achieved by having a status file that FDT writes to as it carries out actions and which
an external user can read. This has the following options:
By default, status file writing will be disabled. Ticking the Enable checkbox will open the Directory and
Name fields for editing; allowing the user to specify where the status file will be created.
[FDTScript Status v1.0] ⇐ The configuration file version
CurrentScript= ⇐ The location of the current script being executed, or the search path being
used whilst waiting
UserID= ⇐ The user name of the person running the copy of FDT writing to this f ile
Machine= ⇐ The machine name the copy of FDT is executing on
LastUpdate= ⇐ The time and date this file was last changed
CurrentStatus= ⇐ The current state of FDT. This will be either ‘waiting’ (if FDT is looking for
a script), ‘processing’ (if FDT has found a script and is using it), ‘error processing’ (if something has gone
wrong with the script) or ‘waiting for user input’ (if a dial og is waiting for user intervention). If FDT exit s
wait for file mode correctly this entry will be blanked
PreviousScript= ⇐ The location of the previously run script
PreviousState= ⇐ The outcome of the previously run script. This will either be ‘COMPLETED’
or ‘FAILED’
JobNo= ⇐ An incrementing number of successfully completed runs. This number will
wrap back to 0 when it reaches 32,768.
When FDT begins a Wait For File session, with status writing enabled, it will first check for the existence
of the specified file. If it is not found then it will be created and FDT will continue. If it is found the file
will be opened and checked. If CurrentStatus is blank (implying that a previous session exited correctly and
that no-one else is using the file) FDT will continue. If an entry is found in CurrentStatus, e.g. ‘Processing’
then FDT will alert the user, via a message box, that a previous session may have crashed or that another
copy is running and using this file also. The option will then be given to continue and overwrite the values
or abort.
