Need help structuring EDGESURF command

[icarus]

I need assistance with structuring parameters for this COMMAND.

My lisp program can issue a COMMAND to draw lines with their ends co-incident. I can then manually use EDGESURF to apply a surface to those lines. No problem there.

Since I supply the vertices to make those lines, how can I tailor this snippet of lisp code, (COMMAND "._edgesurf" "" ) , to apply a surface to those lines automatically?

Thanks in advance
