Subject:      How to enumerate all the variable names in a data set?
Content-Type: text/plain; charset=US-ASCII

Hi, all

Give a multivariate data set, for example, with variables
VAR1, VAR2, ..., VARN.
After I imported this data file/set into SAS, how can I
know the number of total variables and their names respectively?

To be specific, if I want to define an array "TotalVariables" such that each
element of it contains the name of a varialbe, i.e.,
TotalVariables(1) = VAR1, TotalVariables(2) = VAR2, etc.

In some later use, I may refer these variables names in other procedures,like
FOR i =1 to N
    a = TotalVariables(1) + TotalVarialbes(2),
    etc.

That is, I do not want to explicitly write down the variable name at
each iteration.

Hope I can understand myself clearly.
Please help me with your point.

Thanks a lot.

Fred
