[GRASS-user] scripting mapcalc

[achim]

The Problem isn't solved yet!!

I posted an easy example, but calculating with more complicated
scenarios I got these:

r.mapcalc river=if(river[0,1]=4032076 ,4032075,river)
syntax error, unexpected '=', expecting ')'
Parse error

or

r.mapcalc river=if( river=4032076 ||| river=4032076 ,4032075,river)
syntax error, unexpected '=', expecting '@' or '('
Parse error

Any ideas?

Thanks (anyway),
achim
