[GRASS-dev] Issue with double conditional in r.mapcalc (WinGRASS) and real life test of the aconda 7.5dev on Mac

when, in winGRASS, I copy from r.mapcalc:

r.mapcalc expression="rbstreams500 = if( bstreams500 at yann == 2, 1, 0)"

the term is quoted.

when I do in the wxGUI console

r.mapcalc expression=rbstreams500unquoted = if( bstreams500 at yann == 2, 1, 0)

I get an "unable to parse..." error.

how do you conclude that "it is a requirement to run simpler r.mapcalc
statements in winGRASS"?
