I can't help you there since your test case is so very constrained. Except to say that only a very few possible outcomes are going to satify you. Enumerate them and pick one.

Getting back to my test case, you could preallocate 10 to each variable and then distibute the remaining 50 as I indicated. Or you could distribute the numbers one at a time. Cycle though each variable and generate a 0 or 1. Add that to each variable and subtract it from the mass to be distributed.

NAME
incr - Increment the value of a variable SYNOPSIS
incr varName ?increment? _________________________________________________________________ DESCRIPTION
Increments the value stored in the variable whose name is varName. The value of the variable must be an integer. If increment is supplied then its value (which must be an integer) is added to the value of variable varName; otherwise 1 is added to varName. The new value is stored as a decimal string in variable varName and also returned as result. EXAMPLES
Add one to the contents of the variable x: incr x Add 42 to the contents of the variable x: incr x 42 Add the contents of the variable y to the contents of the variable x: incr x $y Add nothing at all to the variable x (often useful for checking whether an argument to a procedure is actually numeric and generating an error if it is not): incr x 0 SEE ALSO
