st: RE: relabeling variables using 2 datasets

use DB2 

forval i = 1/`=_N' { 
	local var = seriescodestata[`i'] 
	local l`var' = indicatorname[`i']

use DB1 

foreach var of var * {

I want to relabel a large set of variables from one dataset (= DB1) using information from a second dataset (=DB2). 

DB1 contains numeric variables with the following names:  vAG_LND_PRCP_MM ,  vAG_SRF_TOTL_K2 , etc.

DB2 contains a string called seriescodestata which contains as values the same variable names as DB1, i.e. vAG_LND_PRCP_MM ,  vAG_SRF_TOTL_K2 , etc 
 
DB2 also contains another string called indicatorname which contains as values the labels I want to give to the variables in DB1

An example: 

DB1
vAG_LND_PRCP_NM                 vAG_SRF_TOTL_K2       etc.           

    327                             13781730

                                                     
DB2
Seriescodestata                         indicatorname

vAG_LND_PRCP_MM                average precipitation in depth (mm per year)

vAG_SRF_TOTL_K2                   surface area (sq. km)     
 
      etc.


Now I'm looking for a program code to automatically relabel the variables of DB1 using the information in DB2
