It's the "^" character that seems to have some problems, because if you
invert your test and do the string adding when the test is true (when
the char IS in the interval 0-9), everything goes correctly and you get
the right result:
IF sSingleChar LIKE "[0-9]" THEN
sFiltered = sFiltered & sSingleChar
ENDIF
Gives 12571234
P.S:
Gambas 2.8.2
