XL Fortran for AIX 8.1
Language Reference
Test whether a string is lexically greater than another string, based on
the ASCII collating sequence.
- STRING_A
- must be of type default character.
- STRING_B
- must be of type default character.
Class
Elemental function
Result Type and Attributes
Default logical.
Result Value
- If the strings are of unequal length, the comparison is made as if the
shorter string were extended on the right with blanks to the length of the
longer string.
- If either string contains a character not in the ASCII character set, the
result is undefined.
- The result is true if STRING_A follows STRING_B in the ASCII collating
sequence; otherwise, the result is false. Note that the result is
false if both STRING_A and STRING_B are of zero length.
Examples
LGT ('ONE', 'TWO') has the value
.FALSE..
