We have added a new pronumerals command to Efofex parameters. You can now define a parameter like:

$x=pronumeral()

This will randomly select a pronumeral from a list of acceptable pronumerals. In this case $x might be turned into a,b,c,… x,y,z with some options (like i and o) omitted. This allows you to create algebraic questions with varying letters.

If you define multiple pronumerals in one set of parameters, the pronumerals will always be sequential.

$x=pronumeral()
$y=pronumeral()
$z=pronumeral()

You might end up with the three pronumerals being a, b and c OR x, y and z OR f, g and h for example.
