_crceprs is an ado file.  Type
which _crceprs
to find it.  You can then inspect it.

From my own inspection, all I can say is that is handles equations.

With some searching, I find it is a "subroutine" to an other ado -- ml_5, 
which is the version-5 edition of ml (maximum likelihood estimation).  (See 
ml.ado and ml_5.ado.)

It is odd that some other do file made use of it.

local if "opt",
is not going to interfere with the Stata -if- command or -if- 
qualifier.  But if it is within a program that has an -if- qualifier in its 
syntax, then this might cause trouble.
