Hi,

Related to my last question is the following. Does anyone have code to write out every possible combination (not permutation) from a given number X taken out Y (X choose Y)?
Any help appreciated. i just cannot seem to get the appropriate number written out.
Thx
Marc

combination

Here is conceptual code, not debugged:
sub combination(x,y)
a = 1
for i = 1 to x
a = a*i
next
b = 1
for i = 1 to y
b=b*i
next
c=1
for i = 1 to x-y
c= c*i
next
return a/(b*c)
end sub

Okay, I took the challenge !
see the attached program, both displaying and storing in a file.
fill the a out of b and press go. you will get the number of combinations and the last one, and you can brouse up and down.:)
