Dear Statalisters,
Could you please help me work out how to attach a two digit numerical prefix to
all my variables? I am preparing to append surveys from different dates but
that have the same variable names, and I would like to distinguish between them
by adding a two digit year prefix (e.g. hhid becomes 95hhid). This will be done
before appending the datasets, so that when I do append I can distinguish
between the variables.
I have not yet taken the Stata programming course (hope to soon), so I'm unsure
where to start.
Thanks,
Reza
