HP 10312D Operating Manual page 30

The 80286 instruction set contains two groups of instructions where the
instruction type is defined in the third byte. In this case, if the third
byte is not stored in analyzer memory, only the group where an
instruction resides
can
be determined. Therefore, the group name,
rather than an instruction mnemonic, is displayed in the mnemonic
display field. These groups are defined as follows:
• 2 byte Grpl - Contains the following instructions:
SLOT
STR
LLDT
LTR
VERR
VERW
• 2 byte Grp2 - Contains the following instructions:
SGDT
SIDT
SMSW
LGDT
LIDT ·
LMSW
Listed below are several abbreviations for normal programming syntax
that have been adopted to reduce the width of the inverse assembler
display field.
dwp -DWORDPTR
wp -WORDPTR
bp -BYTEPTR
fp
-FARPTR
np -NEARPTR
s -SHORT
Note that these symbols are displayed only if the operation size cannot
be
determined from the instruction itself.
To further reduce the field width of the inverse assembler, WCK and
REPeat prefixes appear on the line before the instruction to which they
apply.
