1. I have baseline, 12mon, 18mon variables, that's way the variables are
named tr01-tr28,tr01_12-tr28_12,tr01_18-tr28_18
2. Macro can't be used here
3.when I use "all = sum(of tr01_12 - tr28_12);" the log said"
ERROR: Alphabetic prefixes for enumerated variables (tr01_12 - tr28_12)
are different.
ERROR 71-185: The SUM function call does not have enough arguments."
4.These variables are physically seperated,so I can't use
"all = sum(of tr01_12 -- tr28_12);"
