Madysa | Hallöle together!
I have straight a little bit with regulären squeeze out experimentiert and be there on a small hiatus punched.
The expression (a?|s)* is, How each guide declared völliger Nonsens. (an chain beliebiger length from a, s and/or nothing) accordingly gives Match$ too no Result.
The expression (a{0,1}|s)*, the with regard to content spot-on the same thing How the above-mentioned expression means, doesn't give nothing back. rather crashes the program with Match$ sang- and klanglos ex. No Error Message, no warning nothing. Weder Errorlevel yet Errorproc having helped.
thereupon have I following Overview won:
(a?|s)* -> %MatchLen = 0
(a?|s)+ -> %MatchLen = 0
(a{0,1}|s)* -> crash
(a{0,1}|s)+ -> crash
(a??|s)* -> %MatchLen = 0
(a??|s)+ -> %MatchLen = 0
(a{0,1}?|s)* -> crash
(a{0,1}?|s)+ -> crash
it shining means no individual case To his. ought to it in the Innern of XProfan possible his, then would it helpful, if here, How in each others entrapment, a warning or quite one Error outputted would.
Sincerely,
Nico
PS: when go really %MatchPos and %MatchLen same 0 and when same -1? yet could I there yet no system discover. |
