| <dt><em>Description</em>:<dd>Determines whether one string is lexically greater 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>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. |
