SECTION 3. PROGRAM DOCUMENTATION 



The FORTRAN program consists of the main program: INVENT; nine sub- 

 programs: FRMCLS, LINREG, GUTS, VOLMER, VOLTOT, STRAT , OUTPl, MDSTI, and 

 MDNRIS; and five named common storage areas: COMUNE, FORMCL, REG, OUTl, 

 and STOUT. A description of each along with a variable dictionary are 

 presented below. The program listings are found in Appendix E. 



Common Area COMUNE 



COMUNE transfers job control information from the main program to the 



subroutines. 



Description 



Acreage of compartment 



Prism factor or plot size 



Diameter class size 



Sampling method 



Input file name 



Height measurement length technique 



Conversion factor to transform logs 



to feet 

 Two-tailed area under t-curve 

 Regression option indicator 

 Output title indicating sampling 



method used 

 Compartment title 

 Height measurement top technique 



Common Area FORMCL 

 FORMCL transfers the form class array. 

 Variable Type Dimension Description 



FC Int 32 Form class array 



Common Area REG 

 REG transfers information to and from the regression subroutine. 



Description 



Average height 



Minimum diameter sampled for height 

 Number of height trees sampled 

 Regression slope 

 Regression Intercept 

 Coefficient of determination 

 Standard error of the regression 

 Species code 



Number of non-cull trees above 

 minimum d.b.h. sampled 



■(C*5) indicates the variable is used to store 5 characters.
