8.188 TZOFFSET (Set TOD c
lock offset from GMT)

8.188.1 Function

The TZOFFSET command is used to define the offset of the TOD clock from the current system time. For
GMT use the default value (0000). This is also the correct setting if your system time (the time of the ope-
rating system on which Hercules is running) is set to local time rather than GMT. For time zones west of
Greenwich specify a negative value (example: -0500 for US Eastern Standard Time, -0800 for US Pacific
Standard Time). For time zones east of Greenwich, specify a positive value (example: +0100 for Central
European Time, +0930 for South Australian Time).

HHC02204I tzoffset set to +0100

8.189 U (Disassemble storage)

8.189.1 Function

The U command lets you disassemble storage. The argument specifies the storage address to be dis-
assembled. The length of the storage area can be given as an optional argument. The listed storage area
is formatted as one line per instruction. Every instruction is shown as a hexadecimal string and as read-
able assembler statement. Storage areas that cannot be disassembled (data areas) are marked with
question marks.

8.189.3 Parameter

R

The optional 'R' argument will force real address translation mode instead of current
PSW mode.

V

The optional 'V' argument will force virtual address translation mode instead of cur-
rent PSW mode.

P

The optional 'P' argument will force primary space address translation mode in-
stead of current PSW mode.

H

The optional 'H' argument will force home space address translation mode instead
of current PSW mode.

addr.length

Specifies the address of the storage area that is to be disassembled with starting
address and length (from address addr with the length of length). The length value
must be given in hexadecimal.

addr-addr

Specifies an address range with start and end address (from begin address to end
address) of the storage area that is to be disassembled.
