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.
