thanks nick for your reply. it turns out that -trim()- was not what i was looking for. i managed to get what i want (99% of it in any case) by trial and error with helps from the manual (i looked at append, merge, trim and searched for concat, where i stumbled upon egen option that did the trick). this is the command that i used:

egen studynyr = concat (study year), punct(" ")

i tried to right justify the apperance of studynyr by adding format (%15s)

i.e.: egen studynyr = concat (study year), format (%15s) punct(" ")

but keep getting 'Invalid format'. however when i list the data, appearance seems to be as i like it so i might not have to force right justification but i would still appreciate advice on how to get the right justification command correct.

When you say merge, I guess you mean

Assumed that you have applied -trim()-,
right-alignment is a matter of format,
not of what the values are, nor of how
they are held informally.

You should read up the help on formats.
