Thank you to Maarten and Billy for your quick and helpful replies. I wondered is it possible to alter the syntax so that this can be done in an automated way for many variables?

I can repeat your set of commands for each variable e.g. 

forvalues i = 2/10 {
    local j = 1990 + (2*`i')
    rename r`i'mobila mobila_`j'
	ma drop j
}


forvalues i = 2/10 {
    local j = 1990 + (2*`i')
    rename r`i'lgmusa lgmusa_`j'
	ma drop j
}

Etc. 

However, I have do this for many variables so can you plug in a line with a list of these variables to avoid repeating the command over and over again?

Thank you

Kind regards

Oliver

forvalues i = 2/10 {
    local y = 2*`i' +1990
    rename r`i'mobila mobila_`y'
}
