TERMINAL MODE {
CP} VM controls the terminal attention environment. CP specifies that
one or more attentions force the virtual machine into the CP environment. VM specifies that one attention is reflected to your virtual machine and that more than one attention forces your virtual machine into the CP environment. VK is the for all VM/370 users except the primary system
operator. For more information on this, see "Controlling the
virtual Machine" in section 3. LINESIZE nnn
specifies the maximum allowable line length for terminal
outout. nnn can be a number from 1 through If ON is specified, CP does not separate output
lines into LINESIZE segments. Instead, an output length of 1760 is allowed and CP assumes that the APL system has
inserted the appropriate carriage control characters.
1. The terminal settings you specify with the TERMINAL command are in
effect only for the duration of that terminal session. Whenever you initially loq on, the system defaults are in effect. However, the
settings you specify for line-editing except LINEDEL and KODE are
still in effect when you log on after disconnecting. All the other operinds (MASK, TEXT, APL, ATTN, and LINESIZE) are reset if you log
on after disconnecting.
2. you can define line-editing symbols and status with the TERMINAL command, the LINEDIT operand of the SET command determines whether the VM/370 line-editing functions are on or off.
3. If an error occurs during processing of the command, all functions
preceding the one with the error are in effect. 4. You cannot use any of the letters A through Z, or the numbers 0 throuqh 9, as a symbol (char) in association with any of the
CHARDEL, LINEDEL, LINEND, and ESCAPE operands. 1-!one. 160 IBM VM/310 CP Command Reference for General Users

TRACE Use the TRACE command to trace spec1r1ea macn1ne activity and to record the at the terminal, on a virtual spooled printer, or on
both and printer. If you issue more than one TRACE command, t}1e operands 3.re cumulative; that is, operands specified for the first
time activated, whereas those specified with new modifiers are
updated. The RUN and NORUN operands, however, can be specified in
different TRACE commands for different tracing functions and do not
cause 3. The format of the TRACE command is:
r------------ I 1 r ,

L .J , INSTruct I I CSW I I END I I than one of these activities may be traced by using a single I TRACE :;ommand. For example: , , TRACE SVC SIO PRINTER
L SVC traces virtual machine SVC interrupts. I/O tra::es virtual machine I/O interrupts. PROGRAM traces virtual machine program interrupts. EXTERN ;\L virtual machine external interrupts. PRIV traces all virtual machine non-I/O privileged instructions. SIO tra::es TIO, eLFIO, HIO, HDV, and TCH instructions to all devices. Also traces SIO and SIOF instructions for
nonconsole and nonspool devices only.
ccw traces virtual and real CCWs for nonspool nonconsole device 110 operations. When CCW tracing is requested, SIO and TIO instructions to all devices are also traced. tra::es virtual machine interrupts, PSi instructions, and
successful branches. INSTRUCT tr3.ces all instructions, virtual machine interrupts, and
successful branches.
