Examples of various tree card codings may be found in Appendix A, 

 page ^^. The species code list is found in Appendix A, page 45. 



The data file is constructed by combining the title, plot, and tree 

 cards as follows. The first card in the file is the title card. This is 

 followed by the plot card for plot number 1. The plot card is then followed 

 by all the tree cards for that plot. Next, the plot card for plot number 2 

 is included followed by its tree cards; and so on for the remaining plots. 

 The actual value of POINT (plot number) need not be consecutive. 



An example of an INVENT tally sheet and the resulting data file listing may 

 be found in Appendix A, pages 46 and 47. 



Alternate Form Class File Coding 

 The user has the option to specify a set of alternate form classes. 

 Form class only affects volume when tree heights are measured to a merchant- 

 able top (see page 3) . A file containing these alternate form classes must 

 reside on a disk file. This file consists of four rows and eight columns 



organized as follows: 



Row 1 

 Row 2 

 Row 3 

 Row 4 



Form classes for species 1-8 (see species list in 

 " " " " 9-16 Appendix A, page 45)

Each row is formatted 8(12, X).
