Re: sub-string of string containing '('

[Steve Hankin <hankin@xxxxxxxxxxxxx>]

Hi Arindam,

You can use CANCEL MODE LONGITUDE_FORMAT to eliminate the parentheses:

     yes? define axis/x=-180:180:1/unit=degrees xminus
     yes? say `x[gx=xminus,x=-160],return=xstart`
     160W(-160)
     yes? cancel mode longitude_format
     yes? say `x[gx=xminus,x=-160],return=xstart`
     -160
