Truncation Rule
The truncation rule for the keywords used in headers and parameters is:
•If the longform has four or fewer characters, there is no change in the
shortform. When the longform has more than four characters the
shortform is just the first four characters, unless the fourth character is
a vowel. In that case only the first three characters are used.
There are some commands that do not conform to the truncation rule by design.
These will be noted in their respective description pages.
Some examples of how the truncation rule is applied to various commands
are shown in table 4-1.
