<dt><em>Description</em>:</dt>
|
|
<dd><p>Determines whether one string is lexically less than another string,
|
|
where the two strings are interpreted as containing ASCII character
|
|
codes. If the String A and String B are not the same length, the
|
|
shorter is compared as if spaces were appended to it to form a value
|
|
that has the same length as the longer.
|
|
</p>
|
|
<p>In general, the lexical comparison intrinsics <code>LGE</code>, <code>LGT</code>,
|
|
<code>LLE</code>, and <code>LLT</code> differ from the corresponding intrinsic
|
|
operators <code>.GE.</code>, <code>.GT.</code>, <code>.LE.</code>, and <code>.LT.</code>, in
|
|
that the latter use the processor’s character ordering (which is not
|
|
ASCII on some targets), whereas the former always use the ASCII
|
|
ordering.
