41: What's the significance of the alpha mark (ᵀ) prefix on catalog 2 entries?

[Joe Horn]

I *think* the alpha marked entries are user-code programs which can be listed and copied into RAM. The entries without alpha marks are neither listable nor copyable, because they are in lower-level "m-code".

EDIT: From page 395 in Vol II of the 41CX manual, regarding Catalog 2: "An operation in ROM in an applications or extension module or in a peripheral is provided either as a program or as a function. A program can be copied into user memory, then listed and altered, etc. A function, on the other hand, cannot be viewed — only used. When you list out catalog 2, the computer differentiates the two with the "raised T" in front of programs."
