Hello, I just want to ask how do i generate 6 random numbers ranging from 1 to 100 from which the user indicates the number of combinations to be generated?

JMP has many pseudo-random number generators. Use this one:

Random Integer( 1, 100 );

You can construct a vector with the J() function. Here is a call to produce a column vector of six random variables:

J( 6, 1, Random Integer( 1, 6 ) );

I am not clear what you need when you say "from which a user indicates the number of combinations to be generated."

Thanks for the reply! What i meant is that when a user indicated number of
combinations, say if i input 3 as my combinations, it returns 3 column
vectors of the random numbers generated.

I see. That need is easily handled by the second argument to the J() function.

J( 6, 3, Random Integer( 1, 6 ) );

You can use variables instead of constants, too.

r = 6;
c = 3;
J( r, c, Random Integer( 1, 6 ) );
