I am trying to convert a non-numeric string ID variable to a numeric variable but I get an error message
"too many values". after I use: encode id, gen(copy_id)

My dataset has >75,000 and I understand this may be part of the problem. Please help because I cant do subsequent analysis if this ID variable is not converted to a numeric variable. I have more than 10 datasets to merge on this ID. I cant extract the data using dataex because I am working in a secure environment where I cant copy the data except as an image below.

Example ID's are shown below.

Array

Thanks.
