System Debug Command Specifications M-X
M (modify)
MCP Search PUB, the account library.
MCLG Search LGRP, the logon group library.
MCLP Search LPUB, the logon account library.
MCS Search SYS, the system library.
MCU Search USER, the user library.
For a full description of logical code addresses, refer to the section "Logical
Code Addresses" in Chapter 2.
fname MCU only. The file name of the NM user library. Since multiple NM
libraries can be bound with the XL= option on a RUN command,
:run nmprog; xl=lib1,lib2.testgrp,lib3
it is necessary to specify the desired NM user library. For example:
MCU lib1 204c
MCU lib2.testgrp test20+1c0
If the file name is not fully qualified, the following defaults are used:
Default account: the account of the program file.
Default group: the group of the program file.
cmabsaddr MCA, MCAX only. A full CM absolute code address specifies three necessary
items:
• Either the CST or the CSTX.
• The absolute code segment number.
• The CM word offset within the code segment.
Absolute code addresses can be specified in two ways:
• As a long pointer (LPTR):
MCA 23.2644 Implicit CST 23.2644
MCAX 5.3204 Implicit CSTX 5.3204
• As a full absolute code pointer (ACPTR):
MCA CST(2.200) Explicit CST coercion
MCAX CSTX(2.200) Explicit CSTX coercion
MCAX logtoabs(prog(1.20)) Explicit absolute conversion
The search path used for procedure name lookups is based on the
command suffix letter:
MCA GRP, PUB, LGRP, LPUB, SYS
MCAX PROG
virtaddr MV only. The virtual address to be modified.
Virtaddr can be a short pointer, a long pointer, or a full logical code
