[Gambas-user] why this could not be? error in runtime?

[PICCORO McKAY Lenz]

in the following code:

    strinchar = Mid(strinchar, 1, InStr(strinchar, ")", -1) - 1)

IDE said error invalid argument, but if i do:

    psotionlen = InStr(strinchar, ")", -1) - 1
     strinchar = Mid(strinchar, 1, psotionlen)

works, why?

i wnat to remove the last occurence of a char but bybass some possible
spaces/chars at the end of string
