The preconfigured emulated historic HP3000 for Charon-PAR provides several command files and UDCs (User Defined Commands). For the most part, all customizations are located in the CHARON.SYS group.

This section provides an overview of the following utilities:

Configuring the IP Address

Configuring the Time Zone

The preconfigured emulated historic HP3000 system is configured with TZ="PST8PDT" .

The supplied LOGON UDC (which executes out of UDC.CHARON.SYS ) runs the command file TZ.CHARON.SYS  which in turn sets the TZ system variable local to every Job and Session:

To change the time zone, edit the file TZ.CHARON.SYS, and adjust the system clock using the commands:

xx:yy stands for the time offset of your timezone.

Synchronizing the System Time

The preconfigured system contains the :SYNC utility to update the system time. It must be run as manager.

If :SYNC detects that the system date was updated, it displays the old and new timestamp:

Otherwise it will just display the current date.

Notes:

• By default, :SYNC performs a :SETCLOCK;NOW to adjust any large discrepancies between the system clock, and the current time. It should only be used when starting or resuming an emulated system, and should not be used while date-aware programs or command files are running.
• :SYNC should not be used at or close to midnight - this could result in an incorrect date being set.
• :SYNC is supplied 'as-is', with no warranty as to correct performance.

Default UDCs

The Charon-PAR preconfigured emulated historic HP3000 system includes the following predefined UDCs.

Stromasys provided UDCs in UDC.CHARON.SYS:
