Does the number in "employee1" depend on
a) the number of the current obersavtion,
b) any other variable in that oberservation?
One possible solution:
length employ $ 15; /* defines a character-variable, with enough space for 15 chars */
employ = cat('employee', _n_); /* _n_ = the number of the current obersvation */
Share info about what you would like the end result to look like - multiple observations and variables, multiple variables and one observation. Do you want the "employ" order to be sorted, based on some component of a SAS variable or just based on the raw input occurrences?
Consider using PROC TRANSPOSE if you want to have one observation in total and a unique SAS variable employee1 through employee## for each unique value.
