functions; other subsystems provide their own trace functions. An SCF trace allows
the following options:
Refer to the subsystem-specific SCF reference manual for your particular subsystem
for detailed information about the tracing facility provided by that subsystem.
Using TACL ASSIGN Commands
SCF recognizes the TACL ASSIGN command. ASSIGN is used to associate a
physical file name with a logical file name, allowing you to pass file names and
characteristics to SCF. SCF passes the parameter values to processes that request
parameter values when those processes are started.
TACL can assign the following logical file names for SCF:
For information on how ASSIGN interact with DEFINE statements, see page 4-16.
Assigning the SCFCSTM Custom File
SCF provides the user with the ability to automatically access a command file
containing a set of personalized SCF commands before the start of a session. A file
with the name SCFCSTM located on the user's default volume and subvolume is
executed every time SCF is run in interactive mode. A message is generated when
