is what converts the field from a packed representation to a binary one.

Although normally a question that arises when zoned fields become packed "mysteriously", this is normal behavior for RPG.

All numerics on external files are converted to packed by default.

However, if you place them in a DS by using an externally described DS, then RPG honors the actual data type on the file. Question is what is the "actual type". Because RPG had to handle externally described Binary fields before it had true integer support, the "actual type" treated binary fields as type B. The H-spec option overrides the default behavior and defines the "actual type" as as a true integer. Which of course is what they were to begin with!

Clear as mud right!
