exception of the slash (/) for tops of forked trees. However, the tree extrapolation 

 options provided in STX are not used in NETVSL. Instead, the total height of the stem 

 should be measured so that interpolation of the unseen bole can be accomplished. 



Dendrometer constants B, Q, U, and G are entered on a DENDROMETER CONSTANT CARD 

 that replaces the PROBLEM FORMAT CARD in the felled-tree data sequence. For definition 

 of these constants and for their format, refer to the second STX control card, which 

 can be used unchanged for NETVSL. 



Tree data are entered on two types of cards: a tree input card and subsequent 

 dendrometer input cards. Corresponding variable names in the two programs for the 

 variables on these cards are as follows:

The variable XTERM is used by NETVSL somewhat differently than its counterpart in 

 STX. A blank value for XTERt^ indicates that the current dendrometer card is filled, 

 and more measurements are to be found on the subsequent card. An asterisk indicates 

 the last dendrometer card for a specific tree. A plus sign in XTERM indicates that 

 the last trio of dendrometer measurements was taken at the point where a fork was
