display Line items in a table format

Hi Friends,

Reqirement is, in a table I've 9 columns of PR Item Details to be displayed.

Each column is saparated by a vertical line and each row is saparated by horizontal line.

but for a given Purchase Requisition there may be one line Item or more (Not constant).

/: BOX XPOS '0' CM YPOS '8' LN WIDTH '78' CH HEIGHT 0 CM FRAME 10 TW

I've used the above command to display Horizontal line

How can i dymanically change the YPOS. (After 1st row YPOS '8' LN, 2nd row YPOS '12' LN ....)

Please help me out,

Thanks in advance,
