{ON } OFF APL faN } 10FF TEXT TERMINAL
controls the typing of a masking line at a typewriter terminal
that is not equipped with the print inhibit feature, when a
password is to be entered. If MASK ON is specified, VM/310 types the masking line. If MASK OFF is specified, the masking
line is not typed and it is up to each user to preserve the security of his password. The MASK operand does not apply to the 3215 Console Printer-Keyboard or to similar system
console or display terminals that do not have a print inhibit
feature. Unless otherwise specified, MASK OFF is in effect.
controls the use of APL character translation tables. If APL ON is specified, CP uses the translation tables applicable to
display stations equipped with the APt hardware feature and
typewriter terminals equipped with the standard APL typinq
element. APL ON also applies to the 3161 terminal equipped
with the APL alternate character selection. If APL OFF is
specified, CP uses the normal translation tables (that is, B:O or correspondence code). Unless otherwise specified, APL OFF is in effect. If APt is on, TEXT is forced off.
1. This operand is valid only for 3217 terminals.
2. Tf the TERMINAL APL ON command is issued from a terminal
that is not equipped with APt keys, or if the virtual
macbine is DOt runninq APL when the command is issued,
the results are unpredictable.
If APL ON is specified, the LINESIZE value is overridden (see
the explanation for the LINESIZE operand, below).
controls the use of Text translation tables. If TEXT ON is
specified, CP uses the translation tables applicable to display terminals equipped with the appropriate Text hardware
features= If TEXT OFF is specified, CP uses the normal
translation tables. Unless otherwise specified, TEXT OFF is
in effect. When TEXT ON is specified, APL OFF is forced. MQtg: This operand is valid only for 3211 terminals.
ATTN {
ON } OFF controls siqnaling of an attention interrupt. If ATTN ON is
specified, the exclamation point is displayed when an
attention interrupt occurs. The OFF option suppresses the aisplaying of the exclamation point (!) and carrier return for
those systems that perform special line editing using the
attention key. Unless otherwise specified, ATTN ON is in
effect.
Note: The ATTN operand is terminals ..
not valid for aisplay type

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
