draw grids in the map.

[Namba Takaya <takayanamba7@xxxxxxxxxxx>]

Dear Sir

I tried to draw some grids on the map using "polygon".
However, I could not make it with the following script.
Could you tell me why not?

set region/x=160e:180e/y=40s:60s
shade/nokey/nolabel/level=(0,10000) rose
let AA={168,168.5,168.5,168}
let BB={-50,-50,-50.5,-50.5}
polygon/nolabel/over/line/thick=0.2 AA,BB
polygon/nolabel/over/line/thick=0.2 0.5+AA,BB
polygon/nolabel/over/line/thick=0.2 1.0+AA,BB
polygon/nolabel/over/line/thick=0.2 AA,-0.5+BB
polygon/nolabel/over/line/thick=0.2 0.5+AA,-0.5+BB
polygon/nolabel/over/line/thick=0.2 1.0+AA,-0.5+BB
go fland 5 
quit 

Best Regards,

Takaya Namba
