TOPS-10 Monitor Calls Manual Volume 2 AA-K039D ... - Trailing-Edge

CALLI [OPCODE 047]
22.5 CALLI [OPCODE 047]
FUNCTION
Passes the monitor a function-index for an extended set of monitor
calls, called CALLIs. The negative CALLI indexes are reserved for
customer-defined monitor calls. All non-negative codes are reserved
for use by DIGITAL. Obsolete CALLIs. are marked as such, and they are
not described further in this manual.
The defined CALLIs also have symbolic function-names; in this chapter
they are listed in alphabetical order by symbol name. For example,
CALLI 215 is the CTX. UUO, described in this chapter under "CTX.".
CALLING SEQUENCE
CALLI ac,function-index
error return
skip return
In the calling sequence, you can supply the function-index. The
alternate method of specifying a monitor call is to use the following
syntax:
function-name ac,
error return
skip return
The function-name is the name of the monitor call. For example,
is the function-name for the CALLI with function-index 215.
CTX.
You can use the UU.PHY bit in the ac to indicate that addresses you
specify are physical references.--For monitor calls that take device
names, this bit indicates that physical device referencing is being
used.
To indicate physical references, rather than virtual or logical, set
Bits 18 and 19 in the ac, or include the symbolic representation
(UU. PHY) .
For example, to indicate physical referencing in DIGITAL CALLIs,
as the CTX. UUO, use the following CALLI syntax:
such
CALLI
ac,215!UU.PHY
Or you can specify UU.PHY in symbolic
using the following syntax:
representation of the CALLI
CTX.
ac,UU.PHY
For customer-supplied CAllIs,
representation of UU.PHY:
remember to use the negative
CALLI
ac,-l,-UU.PHY
