gmap help plz

[wild8900]

I made a gmap:

GRMAP001
WIDTH 7
HEIGHT 5
LEVELNAMES
"irataworld_a01.nw","irataworld_b01.nw","irataworl d_c01.nw"
"irataworld_a02.nw","irataworld_b02.nw","irataworl d_c02.nw"
"irataworld_a03.nw","irataworld_b03.nw","irataworl d_c03.nw"
"irataworld_a04.nw","irataworld_b04.nw","irataworl d_c04.nw"
"irataworld_a05.nw","irataworld_b05.nw","irataworl d_c05.nw"
LEVELNAMESEND

I only made and linked the first row (a01-c01)
but I know I need to use loadmap irataworld; (irataworld is gmaps name)
but where do I put that command?
