st: String problem
I have a macro `covars' which is a list of variables, var1 var2
var3... var19 var20
I would like to exclude the last variable, var20, from `covars' so
this is what I did:
gettoken dropped revcovs: revcovs
I'm sure there must be some way more elegant, just that I can't think
of it. Any suggestions?
Elegance aside, my variable list, if too long, would get truncated
because I assigned the macro revcovs with the "=" sign in the first
line of my above code. Is there anyway to avoid the "=' sign in that
Thanks in advance for any suggestions!
