Hello, Dan;
I'm glad you made it!
Another small notice about USER mode and assignments.
There are two basic types of "programs" in any HP41: those writtne by the user and those available in ROM modules. Financial Decisions Pack is a ROM module wiht many programs that you can use, list and load into RAM (COPY function).
While these programs are sored only in ROM, their "label" is treated by the system as an XROM function and may be assigned to as many keys as you can asign their name to. But if you have a program in RAM with a global labels, i.e., lable with ALPHA characters, these labels can only be assigned to one key at a time.
If you create a program with a LBL'GO anywhere, each time you assign 'GO to a new key will clear previous assignment. This is because global labels store the assignment in the LBL function itself, and general functions store their assignments in part of the calculator RAM (one register is needed to hold two assignments).
If you already know about this, forgive me; maybe others will find it helpful.
Cheers.
