Purpose
Test whether a string is lexically
less than or equal to another string, based on the ASCII collating
sequence.
Argument type and attributes
- STRING_A
- must be of type default character.
- STRING_B
- must be of type default 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 the strings are equal or if STRING_A precedes
STRING_B in the ASCII collating sequence; otherwise, the result is
false. Note that the result is true if both STRING_A and STRING_B
are of zero length.
Examples
LLE ('ONE',
'TWO') has the value .TRUE..
