This command will return a float representing the Y position of a vertex of the locked vertexdata.

Return Float=GET VERTEXDATA POSITION Y(Vertex Index)

Vertex Index

Integer
This value is an integer number such as 1.

This value is a float number such as 0.5

rem Create simple plain and read its 4 vertices (plus any indices)

if get maximum vertex shader version()>0

 make object plain 1,100,100

 vmax=get vertexdata vertex count()

 for v=0 to vmax-1

  x#=get vertexdata position x(v)

  y#=get vertexdata position y(v)

  z#=get vertexdata position z(v)

  nx#=get vertexdata normals x(v)

  ny#=get vertexdata normals y(v)

  nz#=get vertexdata normals z(v)
