HP-41 questions



#2

In the programs http://www.hpmuseum.org/software/41/41roman.htm there are numerous instructions "DSE X", I am unable to enter it on my CX. Is "X" here a "synthetic" register, so may I replace it with any numeric one?

Is it possible to enter function name into program from Catalogue directly?

No. X, Y, Z and T (and also L = LastX, for that matter) simply are the usual stack registers. Yes, the '41 can also use the stack for commands like DSE, ISG, STO, RCL, X<>, VIEW and others. It is not limited to the regular numbered standard registers.

If you use these commands, the stack registers can be addressed by pressing the decimal point [.] before X, Y, Z, T or L. At this point, the '41 shows a "ST" to indicate that you are about to use a STack register.

  [XEQ] [ALPHA] D S E [ALPHA]
=> DSE _ _
[.]
=> DSE ST _
X
=> DSE X ; as usual, the X is on the "6" key

No. At least not with a standard '41.

Yes, it you have a W&W CCD module installed, or alternatively the CCD OS/X ROM block in an active page of a RAM box.
