Hi,

I'm using the r.mapcalc module inside of a script.
I'm using unix shell commands with constructs for iterative execution (for a 
in - do) and so I have a variable ($a) that I use in the input, output and 
options setting of the GRASS commands.
I have no problem usually but if I use r.mapcalc like in the example I have 
this error message:

GRASS 5.7.cvs:~ > r.mapcalc<<EOF
> 'cost_'$a'_ok'=if(sir_clump!=0,0,'cost_'$a'')
> EOF
parse error, expecting `'=''
Parse error

Someone can explain me how to use variable in r.mapcalc?

Thanks of all
