Begin; Change - IBM Professional Series User Manual

BEGIN
3. CP ignores the ATTN and REQUEST commands if an
110 operation is in progress at the console or if other
interrupts are pending for your virtual machine. This
condition may result if you issue the ATTN or
REQUEST command by means of DIAGNOSE X'8'.
Use the BEGIN command to continue or resume execution
in the virtual machine at either a specified storage location or
the location pointed to by the virtual machine's current
program status word (PSW). The format of the BEGIN
command is:
I
Beg in
[hexloc]
Where:
hexloc
is the hexadecimal storage location where execution
is to begin.
Usage Notes:
1. When BEGIN is issued without hexloc, execution begins
at the storage address pointed to by the current virtual
machine PSW. Unless the PSW has been altered since
the CP command mode was entered, the location stored
in the PSW is the location where the virtual machine
stopped.
2. When BEGIN is issued with a storage location specified,
execution begins at the specified storage location. The
specified address replaces the instruction address in the
PSW, then the PSW is loaded.
CHANGE
Use the CHANGE command to alter one or more of the
attributes for a closed spool file. The format of the
CHANGE command is:
7 -12
