Hello,

I am running GRASS GIS 6.5 and want to run a python script
including a mapcaluculator-expression of a simple formula:

A=if(B,C)

grass.mapcalc("$upstream_shreve = if(${upstream_part},${shreve})",
                  upstream_shreve = options['upstream_shreve'],
                  upstream_part = options['upstream_part'],
                  shreve = options['shreve'])

but that isn't working... I don't know whats excaclty the problem....

hopefully you can help me

thanks
Johannes
