Truncation
Rules
The truncation
rule
for
the
mnemonics
used
in
headers and
alpha
arguments
is:
The
mnemonic
is
the
first
four characters
of
the
keyword
unless:
The
fourth
character
is
a
vowel,
then
the
mnemonic
is
the
first
three
characters
of
the
keyword.
This
rule
will
not
be
used
if
the
length
of
the
keyword
is
exactly
four
characters.
Some
examples
of
how
the
truncation
rule
is
applied
to
various
commands
are
shown
in
table
4-1.
