st: How to reference tempvars across ML programs?
ML programs written in ado file form comprise a main program and
another program (or programs) called each iteration to evaluate the
likelihood. Advice please about how to reference in the likelihood
evaluation program(s), temporary variables that are created in the main
In myp1.ado I currently have code like
generate z`i'`d' = uniform()
generated in a loop, where `i' = 1,...,$M, and `d' = 1,...,$D (and both
$M, $D are user-defined). The -ml- command in this file calls
myp1_ll.ado in which I do calculations referring to each variable
z`i'`d', again within a loop over `i' and `d'.
I can make the program work in this way, but note that the "z" prefix
means that I am generating permanent variables with a specific name
(a Bad Thing as far as programming is concerned).
How can I make these indexed variables temporary but still refer to
I've played around with using -tempvar- commands within myp1.ado, but I
don't seem able to refer to these (suitably indexed) in myp1_ll.ado.
(Note too Manual [P] macro entry, p. 133, that warns that one cannot
suffix temporary variables with additional characters and use them.)
Another idea was to use global macros to hold the variable names
created, but again I couldn't get this to work.
thanks for any advice and suggestions.
