Did that doc precede or follow the "bugfix"?  On page 13-132, my FILEPRO PLUS 3.0 
manual (undated) says, under "Restrictions,"

	Do not use the row/column parameter with the at-sign (@). If
	both are included in the SHOW command, the cursor-position
	information is ignored.

The word "ignored" is a holdover from editing the earlier text to state the opposite. 
IAC, since the program stopped pausing with a "press enter to continue", so that the 
screen was immediately redrawn, it was not obvious that the "@" was included in the 
displayed text. :-)
