As an example, assume the following form classes were desired: 



All pines 80 



Hemlock, Spruces, Ash, 78 



Black Cherry 



Balsam Fir, Tamarack, Cedar 



Other Softwoods , Sugar Maple 76 



White Birch, Yellow Birch 



All other species 75 



The data file that would implement these form classes is: 



80 80 80 78 76 76 78 78 



80 76 76 76 75 78 75 75 



75 78 76 76 75 75 75 75 



75 75 75 75 75 75 75 75 



Running the Program 



Running INVENT consists of interactively supplying the program all job 

 control information. This information includes: alternate form class 

 specification (if desired), diameter class size, number of strata, confidence 

 level, input file name for each strata, sampling method (point or plot), 

 basal area factor or plot size, method of height measurement, acreage of 

 each stratum, and title of combined strata output (if more than one stratum 

 sampled) . 



This interactive portion of the program is self-explanatory. The program 

 asks the user certain questions while listing the possible answers. The 

 number of questions asked depends on the options used and the number of strata 

 sampled. The questions are asked as each data file is read and processed. 

 Under conditions of heavy computer usage there may be a time lapse of as much 

 as two minutes between certain questions. This process is best explained by 

 example. 



Tables 1-16 are part of a 59 page inventory report based on a 3 compart- 

 ment cruise of Whitaker Woods in North Conway, N.H. Listed below is the 

 entire user-program dialogue that produced that output. Each of the questions 

 asked has been numbered for reference and user responses are underlined. 

 Most questions are totally self-explanatory and therefore only a few will be 

 discussed.
