I cannot make the backwards search work. Did I do anything wrong?
Tried with Desktop 2019 and 2018. It worked in the past as I remember.
I think it's a bug on the function or the documentation. I remember that I reported the inconsistency to Safe support four years ago, am surprised the issue is still outstanding.
Forgot the case number, but I found out this workspace which I sent to Safe in order to describe the issue at that time.

Hope someone from Safe clarifies this. @danatsafe

@takashi Unfortunately the current doc is misleading. FindRegEx can't search backwards but the start of the forward search can be set from the end (counting backwards). @jingking If you expect FindRegEx to return 0 for 12345L, then instead try
@Evaluate(@StringLength(12345L)-1-@FindRegEx(12345L,L))@takashi Unfortunately the current doc is misleading. FindRegEx can't search backwards but the start of the forward search can be set from the end (counting backwards). @jingking If you expect FindRegEx to return 0 for 12345L, then instead try
