Appendix A:


Routines written by RBR
main() program ASSP   main program, opens files, accesses other routines, etc.
cons_test()	      given an alignment, and a property matrix, determines the 
			  conservation
nCr() factorial()     calculator routines to find nCr and x! 
readprop()	      reads in property type table

Routines written by GJB:
Agetbloc()	      read in a vertical alignment file (AMPS format)
comb()		      generate all possible combinations of R from N
clus2blc()	      program to convert CLUSTAL format to BLOCK format
msf2blc()	      program to convert MSF format to BLOCK format
gjutil()	      Geoff's utility routines

Routines based on Numerical Recipies(*):
ran3()		      generate random number between 0 and 1
