Think he wants to do a PING from an RPGLE program.

Maybe the system API can be used for that. Or using QSH.

Kind regards,

Thanks Jonathan for this great regular expression for offline structure controls that allows me to do a pre-check but here I would like to check the existence of this URL in an RPG program.

Sorry, should have been slightly clearer when I said it was possible to
use C, SQL, something else... from within RPG you can call C API's and
SQL. Both of which provide methods to do regex matching.

Some pointers to get you started.

C

https://www.ibm.com/developerworks/community/forums/html/topic?id=355b0d77-a5e6-46c2-af6e-8ffe9641f497
SQL

Obviously you could do it the long way with RPG checks and substs and
scans and trims... but why re-invent the wheel :-)

Hello everyone

I need to control that a URL entered by a user is valid.
Would anyone have an example of RPG code for this?
I'm going to have to say that regex might be the best way (I know nothing about regex) as there are a good few examples on the interwebby.
(https://www.regextester.com/98055)

Likewise, there are examples of using regex from within RPG such as via SQL (possibly others, maybe C, or an API?).

The expression required is (remove quotes) "(ftp|http|https):\/\/(\w
+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?"

Hope this helps.
