How to replace long list value by order

[Tan Nguyen]

Hi all. I'm strunggling with replace value. For example, I want to replace "services_rehab_challenges_0" to "serv_rehab_chal_0", "services_rehab_challenges_1" to "serv_rehab_chal_2", ......., "services_rehab_challenges_*" to "serv_rehab_chal_*". Because my value list very long so I really appreciate any suggestions to do these task. Thanks all!!!!

replace variable = subiinstr(variable, "challenges", "chat". 1)

You also refer to replacing 1 with 2, which can be done, but looks more likely to be a typo in the question.

Sorry about typos in #2. Should be

 
 replace variable = subinstr(variable, "challenges", "chat", 1)
