Table 10-7. Derivation of the LPTR Bit Pattern
Parameter Type Action
BOOL 0.1 if TRUE, 0.0 if FALSE.
U16
U32
SPTR
Set the SID part to zero. Right justify the original value in the low-order
32 bits of the offset part with zero fill.
S16
S32
S64
Set the SID part to zero. Right justify the original value in the low-order
32 bits of the offset part with sign extension.
LONG Class Transfer both parts of the address unchanged.
EADDR
SADDR
Transfer the SID part unchanged. Transfer the low-order 32 bits of the
offset part.
STR Transfer the ASCII bit pattern for the last eight characters in the string.
Strings shorter than eight characters are treated as if they were extended
on the left with nulls.
