findfilesseuThe code examples in this article is based on the first version of the FindFiles() procedure. The FindFiles() procedure has been updated to Totally Free RPG and a bug have been fixed. You will find the source code, example and build script here.

I am working on a utility and I wanted to add the ability to search for files in the IFS. That is, I wanted my utility to search the entire or relevant parts of the tree structure (including sub-directories) seen from the IFS’s point of view. Had it just been a search for objects in the libraries, a DSPOBJD command could do the job. But my ambition was that the search should work anywhere in the IFS and, of cause, only find objects matching a name mask that I would provide. Sounds like a reasonable requirement, don’t you think?

This function searches the IFS for files and directories having a name that matches the mask 🙂

When a matching file is found, a ‘File Found’ function/procedure is called. The ‘File Found’ function/procedure is one that you supply. An example is supplied.

ILE RPG function to convert a string to upper/lower case

» Please note, that this article has been superseded by this one: ILE RPG function to convert a string to upper/lower case – fast. If you convert many fields/records in one go, these procedures are way faster that doing it using SQL 😉

The two functions, contained in this module, converts a string to upper and lower case. The advantage of these two ILE RPG functions is, that the conversion includes national characters 🙂 For us Danes, the letters ‘æøåáé’ will be converted to ‘ÆØÅÁÉ’.

What iSeries library is a CL program loaded from?

Most often when you develop a CL program, it is in order to use it as a ‘driver’ program for a RPG/ILE RPG/COBOL/C program. In order to make sure that the RPG/ILE RPG/COBOL/C program is called correctly you have to add the library containing the CL and RPG/ILE RPG program in question, or you can hard-code the library on the CALL command.

This is, however, not a flexible solution, as the CL and RPG/ILE RPG program cannot be copied to other libraries because the CL program will always call the RPG/ILE RPG program in the library hard-coded on the CALL command :-

Fortunately help is on it’s way 🙂 Continue reading →
