#2986: r.mapcalc with same variable on LHS and RHS
-------------------------+-------------------------
Reporter: mankoff | Owner: grass-dev@…
Type: defect | Status: new
Priority: major | Milestone: 7.0.4
Component: Docs | Version: 7.0.3
Keywords: r.mapcalc | CPU: Unspecified
Platform: Unspecified |
-------------------------+-------------------------
It appears the following is valid syntax:
{{{
r.mapcalc "x = x + 1" --o
}}}
But a GRASS developer has said ([http://gis.stackexchange.com/a/109763/609
source]),
{{{
Note that you shouldn't use r.mapcalc like this (read from and write in
the same map):
r.mapcalc "old = old + 10" --overwrite
}}}
If this is the case, this seems like it **important** and should be
included in the documentation.
