<div>Hi, NCL users:</div>
<div> </div>
<div>Sorry. I probably asked a similar question which I don’t rember. Can
someone explain for me what the following * in lat[*] and the number 1 in Opt[1]
means?</div>
<div> </div>
<div>procedure rectilinear_to_SCRIP(FName[1]:<wbr>string,lat[*]:numeric,\</div>
<div>8 lon[*]:numeric, Opt[1]:logical)</div>
<div> </div>
<div>function isatt_logical_true(Opt[1]:<wbr>logical,AttName[1]:string)</div>
<div> </div>
<div>The square looks like list, the it is defined as logical or numeric
variable.</div>
<div> </div>
<div>thanks,</div>
