Recursion & loops

[Ludovic Court?s]

Hi,

I'm trying to create an empty table that would fit one whole page.
Optionally, I'd like to have the row number printed in the first column of
each row.  I tried to define a loop that would create the rows for me but I
failed.  Here is the loop:

  def @Loop
          named from { 1 }
          named to   { 20 }
          body  @Body
  {
    from @Case
    {
      to @Yield { @Body }
      else @Yield { @Body @Loop from { @Next from } to { to } { @Body } }
    }
  }

Inside my @Tbl, I just write the following:

  @Loop from { 1 } to { 20 } { @Rowb }

where @Rowb is the (empty) row I want to add.  However, I end up with the
following error:

  fatal error: maximum depth of symbol expansion (1000) reached

Preceding the @Loop invocation with an @VLimited removes the error but then
nothing gets printed.

Also, I don't know how I could get the rown number printed in the first column
of the row, doing something like @Loop ... { @Rowb A { @RowNumber } }.

Any ideas?

Thanks,
Ludovic.
