Handling is similar to data exceptions, however we can always store the
VXC into the lowore and the FPC:
z14 PoP, 6-20, "Vector-Exception Code"
When a vector-processing exception causes a pro-
gram interruption, a vector-exception code (VXC) is
stored at location 147, and zeros are stored at loca-
tions 144-146. The VXC is also placed in the DXC
field of the floating-point-control (FPC) register if bit
45 of control register 0 is one. When bit 45 of control
register 0 is zero and bit 46 of control register 0 is
one, the DXC field of the FPC register and the con-
tents of storage at location 147 are unpredictable.
