Hi SAS community,    I have a variable in a dataset called "id" (short for identification).    Observations under this variable are recorded as such: 001AB, 002DK, 003LB, 004KC, etc.     For clarification, the numeric digits refer to the participant number, while the letters refer to the initials of the individual participant in question.    I would simply like to "get rid" of the letters within these id's.    Therefore, 001AB would become simply 001, 002DK would simply become 002, and so forth.    Could anyone point me in the right direction for a solution to this problem?   Many thanks!     ...
