I have a wide form of longitudinal dataset recording scores of multiple times like this
ID Group Time0 Time1 Time4 Time9 Time15 Time24 Time37 (...)
1 A 10 15 17 9 8 29 9
2 A 21 39 32 . 33 31 23
and I'm using array to convert this dataset to convert this dataset to the long form, like that
ID Group Time Score
1 A 0 10
1 A 1 15
Since there are lots of Timepoints in the wide data, and the numbers are irregular, I have to write a ton of "if...else" following the array, just to change values of variable "Time" in the new dataset.
I wonder if Is there any way to just extract the number following the variable Time0 Time4... and put it as the value in the new Time variable?
Thanks so much!

I did the following code and it get the jobs done!
time = input(compress(vname(array[i]),,'kd'), 6.);
