HB_RAT(cToken, cString, nStart, nEnd) ignores nEnd, if it is "out of
bound". I feel is more natural "out of bound" string be an empty
string.
Example: I want to iterate over all "/" characters from right to left.
cPath := "/aaa/bbb/ccc"
nI := LEN(cPath)
DO WHILE(nI := HB_RAT("/", cPath,, nI)) > 0
? nI
nI--
ENDIF
But this is endless loop:
9
5
1
9
5
1
...
I would expect HB_RAT("/", cPath,, 0) to search "/" in a empty (zero
length) substring of cPath, and thus return 0.
Does anyone has objection against such change?
No, just pls make sure new behavior is in sync with HB_AT().
[ AFAIS, HB_RAT() is currently different from HB_AT(),
in this case it should definitely be synced. ]
Brgds,
Viktor
