Re: RPG pre-compile Diagnostic check

Just to add, if it is SQL you are looking at, there is an Embedded SQL Programming manual, 7.2 version is at https://www.ibm.com/docs/en/ssw_ibm_i_72/pdf/rzajppdf.pdf - there's a section on Basic processes of the SQL precompiler that might explain more.

Hi Alan


The only pre-compiler I know is the SQL pre-compiler - is this what you refer to? That pre-compiler converts embedded SQL into calls to various SQL-engine programs, among other things like checking for any errors in the code - could be invalid SQL syntax, for example.


Hope that makes sense and is what you are asking about! :)

Can someone explain exactly what the "diagnostic check" pre-compiler
does in an RPGlE compile?

Thanks!
