Hello, I have a variable named "fac_code" which contains code delimited by space. However, there are some errors in code where there is no delimiter between code. The code starts with a letter and followed by some digits. I would like to fix it by adding space between codes. For example,   fac_code K111I001 C01 A01B001   I want it to be K111 I001 C01 A01 B001   I did something like data a; set a; if prxmatch('/[A-Z](\d+)[A-Z](\d+)/)', fac_code)>0 then fac_code_clean = catx(' ', char(fac_code,2)) but it does not work   Any help is appreciated! Thanks in advance     ... View more
