st: using a string variable with use and save command

[Kushan Thakkar <kthakk4@gmail.com>]

I want to write a program that reads a list of files one by one
(through a for loop) while making changes. In order to do so, i will
need to supply a the file name as a variable with the use command.

For example:

gen filestr = "file name here"
gen fileno = 1
gen infile = filestr + fileno
use infile, clear

Could somebody please help me with the correct syntax for doing this?

Thanks.
Kushan
