Save Base64 string to jpg on IFS (in RPGLE)

Question

I have an RPGLE variable that contains a BASE64 string of an image. Does anyone know how I can save that data on the IFS as a jpg?

you're talking about the language RPG from IBM? I retagged the question for you, because the IFS tag is for something different and therefore misleading here. — jps, Sep 18 '20 at 12:39

Before saving to the IFS as suggested by @jtaylor___

You'll need to decode the BASE64 string back into a binary value.

Scott comes to the rescue again with Base64 Encode/Decode for ILE RPG

Also available are the Apache Portable Runtime (APR) base64 routines

Once you have the binary data in a variable, you can write it out to the IFS with JPG extension...

True about decoding first. I use Scott's library for encoding. Works like a champ. – jtaylor___ Sep 18 '20 at 17:19

Check out Scott Klement's "Working with the IFS in RPG IV" (https://www.scottklement.com/rpg/ifs_ebook/). It should be a simple matter of using the write() method to file with a JPG extension.
