Adding suffix to all variables after a given variable

[Ernestina delPiero]

I am running the same code on different datasets. They all contain four initial variables: year, country, object, period, and then a list of city codes. Each file contains a different number of city codes. I would like to add a suffix to each city code, but want to have code that is general enough that it could apply to any of my files. The ideal scenario is one where all variables after the variable 'period' would contain a suffix.

How can I specify that all variables, after a given variable (in this case 'period'), should be renamed to contain the suffix "c_"?

Thanks

Perhaps it might easier be to rename all variables and then change back the first four:

rename * c_*
rename c_year year
rename c_country country
rename c_object object
rename c_period period

I would not rely on the ordering of variables. If the four names are always the same, code

ds year country object period , not
rename (`r(varlist)') (c_=)

I assume by suffix you actually mean prefix.

Thank you Igor Paploski and daniel klein. Both ideas work well! (And yes, I meant prefix.)
