Purpose
Test whether a string is lexically
less than another string, based on the ASCII collating sequence.
Argument type and attributes
- STRING_A
- An INTENT(IN) CHARACTER
- STRING_B
- An INTENT(IN) CHARACTER
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 precedes 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
LLT ('ONE',
'TWO') has the value .TRUE..
