S - The CM Stack Window
address shown at the left side of the window is relative to the indicated base. (Refer to
the QM command.)
• QDST - QDST is the data segment for the Q window. In most cases, this is the same as
the stack DST. This window may be aimed away from the stack, in which case this value
indicates the DST being viewed.
• Level 0 - The current stack level. (Refer to the LEV command).
window body line(s)
• offset: - The starting CM word offset for the line of displayed values. The values may be
unsigned (default) or signed (relative to the address mode base). See the QM command
for details.
• values - The actual data values are displayed in the current output base of the window.
• Q> - Indicates the location of Q. The stack marker (at Q-3, Q-2, Q-1, Q) is typically
underlined. (Refer to the ENV MARKER command.)
• <S - Indicates the location of the current top of stack. The TOS value is typically
underlined. (Refer to the ENV MARKER command.) If the TOS value has changed, the
enhancement for the changed value will overwrite the enhancement for the TOS
indicator (as in our example).
S - The CM Stack Window
The stack window tracks S, the current top of the CM stack (TOS).

• S % - Abbreviation for the window and the current output display radix.
• (DB mode) - The address mode for the window. This can be DB, DL, Q, S,orDST. The
address shown at the left side of the window is relative to the indicated base. (Refer to
the SM command.)
• SDST - SDST is the data segment for the S window. In most cases, this is the same as
the stack dst. This window may be aimed away from the stack, in which case this value
indicates the dst being viewed.
• Level 0 - The current stack level. (Refer to the LEV command.)
