[GRASSLIST:1604] x,y to ll

[E. Koster]

Dear grasslist,

Since my work is focusing on towns I never thought I would need any
specific projections, so I have set up my grass locations in the x,y
system. For the town of Groningen (the Netherlands) somewhere 233908E
and 582059N (position of the main church in the center).
Now I need to know the lat/lon coordinates. gc2ll is asking me for
x,y,z. What coordinates should I give here, e.g. for the given point of
the church. Or is this not the right way to do so....

Thank you in advance,
Elwin Koster
