yes like : Private Function ModifyThat(byRef i as integer) as boolean
i+=6*4 catch return true end to use it if not Modifythat(ByRef iMyVal) Then Print iMyVal sometime it can be usefull to catch the error in the calling function 2011/9/9 Jussi Lahtinen <jussi.lahti...@gmail.com>: > After I read what Fabien wrote, I realised what you meant and I think you > misunderstood my problem. > > My problem is *not *that I have to write byref to function declaration and > to function call. > My problem is that if I forget to write byref to function call, I will get > silent bugs. > > I think either byfer should be mandatory to write to function call, or there > should be warning from missing byref keyword. > > Jussi > > > > 2011/9/8 Benoît Minisini <gam...@users.sourceforge.net> > >> > Hi! >> > Quick thought; it would be nice to have compiler warning if "byref" is >> > missing from function/sub call. >> > I know using byref is optional, but so far I have only forgot to add it. >> > >> > Example: >> > >> > Private Sub Test(Byref x As Integer) >> > ... >> > >> > And you can call it; >> > Test(i) >> > Or; >> > Test(Byref i) >> > >> > >> > Jussi >> >> By having to specify ByRef in the caller, you can't forget that the >> function >> will modify your variable (forgetting that leads to hard-to-fix bugs) and >> it >> help readers of your code. >> >> I added ByRef to Gambas only to help porting VB projects.
