You could copy the input using argname, for example:
ID = genseries(argname(depY), depY)
Then you should be able to use the ID number also in the OLS command.
Of course the copying doesn't make it 100% efficient, but the loss
should be minor.
Or if you don't mind using string substitution, you could use
"rename":
<hansl>
function matrix myfunction (series depY, list X)
string realname = argname(depY)
rename depY @realname
ols @realname X
...
end function
</hansl>
