17 | .. function:: LGE(STRING_A, STRING_B) | |
18 | ||
19 | Determines whether one string is lexically greater than or equal to | |
20 | another string, where the two strings are interpreted as containing | |
21 | ASCII character codes. If the String A and String B are not the same | |
22 | length, the shorter is compared as if spaces were appended to it to form | |
23 | a value that has the same length as the longer. | |
24 | ||
25 | :param STRING_A: | |
26 | Shall be of default ``CHARACTER`` type. | |
27 | ||
28 | :param STRING_B: | |
29 | Shall be of default ``CHARACTER`` type. | |
30 | ||
31 | :return: | |
32 | Returns ``.TRUE.`` if ``STRING_A >= STRING_B``, and ``.FALSE.`` | |
33 | otherwise, based on the ASCII ordering. | |
