Vector Module Registers
The vector module registers consist of the following:
Internal processor registers (IPRs) (see Table 7–1)
Vector indirect registers (see Table 7–2)
Vector Length, Vector Count, and Vector Mask control registers
This chapter explains how to access the registers and then shows the
registers. See your System Technical Users Guide for complete descriptions
of the registers.
7.1 Console Commands to Access Registers
From the console, the EXAMINE and DEPOSIT commands are used to
read and write the IPRs and the vector indirect registers. The vector data
registers can also be accessed from the console. The qualifiers differ:
/I to read and write the IPRs
/M to read and write the vector indirect registers, except for the 16
vector data registers
/VE to read and write the vector data registers
From the console, the Vector Length, Vector Count, and Vector Mask control
registers can be specified as VLR, VCR, and VMR after DEPOSIT and
EXAMINE commands with no qualifiers. VLR and VCR are 7-bit registers
(Figure 7–1), and VMR is a 64-bit register (Figure 7–2).
