RE: st: how to generate many dofiles in a program?

["Hauck, Katharina D" <k.hauck@imperial.ac.uk>]

Thanks Kit, works! I had the problem that ...

file write myfile "use "`data'/my_auto.dta", clear" _n

....did not work, but that was easily fixed by replacing with...

file write myfile `"use "`data'/my_auto.dta", clear"' _n

Katharina.

I want to generate 300 STATA do-files in a program, varying two macros for each of the separate do-files.  There is a thread on that issue, and apparently the file write command can be used to created STATA do-files in a program, but it is not clear to me how exactly to do that.
 
As background: I need to run a very computationally intensive job on a high performance computer in parallel. I run a regression repeatedly with varying combinations of regressors, and save the results. I want to split the job in 300 separate batches, and per batch, I want to run 1000 regressions.  In need to vary for each do-file the set of regressors (I use the tuples ado from Nick Cox).  Our HPC does not accept the user written parallel programming ado, so I need to farm this out myself, and I see no other solution but to create 300 do-files from one master do-file, changing the range of tuples to be estimated in each of the 300 files.


Something like

sysuse auto, clear
tuples headroom-turn
loc nt `ntuples'
forv i=1/`nt' {
	file open myfile using tuple`i'.do, write replace
	file write myfile "sysuse auto" _n
	file write myfile "reg price `tuple`i''" _n
	file write myfile "exit, clear" _n
	file close myfile
}
