The routine lists all the 64 board squares in algebraic notation, adding the piece name and the color if a piece is there, or "EMPTY" otherwise. The color depends on whether HP plays white or black, as determined by flag 04.

Code:

1    LBL "SHOW"
2    21,084
3    STO 00
4    LBL 10
5    XEQ 00
6    ISG 00
7    GTO 10
8    RTN
......

It looks like you are XEQ'ing some internal routine in the chess module ?( 21,084).

What does that routine do ?

Is it the code at 651D ?
(I used the V41 edit /info command on the chess module, routine 21 shows 651D)

p.s. Do you have commented source for the chess module .. that you'd like to share ?
