[split] HP-41CX - FC? Instruction - was HP 35S

[The Don]

The
FC? IND 37 is for my HP41CX
even when i try to use XEQ in front of it, is comes up with message Non-existent.
How do we enter program steps involving Alpha Characters for instructions that are not on the keyboard, like FC? or FC?C, to make it recognize that this is more than just an Alpha string
