Dear List --

I am trying to automate a bit of code to handle two or more equations. I
would like the number of equations to be be known when ml is called to set
the upper index of the loops.

For example, I would like stata to pick up the value of Neqn (from the code
below) at the time ml is called, instead of having to fix it (to the value
4) in advance.

*
* extract Xb = b*X and Xa = a*x for all Eqns.
*

local Neqn  = 4
local Nprob = `Neqn' - 1

forval i = 1 / `Neqn'{
tempvar xb`i'
mleval `xb`i' '   = `b', eq(`i')
}


Thanks
Dan
