Re: st: String vector

["Michael Blasnik" <michael.blasnik@verizon.net>]

I'll tackle the first problem.  When you build up the string in local groep and 
local sterfte you must enclose references to other locals in quotes.

Your code:

local groep="lft"+string((`y'-1)*5)+"_"+string(`y'*5)+`gesl';

will not work since +`gesl' at the end is expanded to +_m, and Stata doesn't 
know what _m is.  Try

local groep="lft"+string((`y'-1)*5)+"_"+string(`y'*5)+"`gesl'";
local sterfte="stf"+"`gesl'";

although this last line can be just

local sterfte="stf`gesl'";
