WP34S - f SLV used with user selectable variables

[gomefun2]

If I want to store a single number such as 0.8175728566800069800087820069820087 for ASCII. do I have to do something like:

001: LBL A
002: #009 // number of variables
003: SDR 003 // putting 009 into fff, as in cccccc.fffii
004: STO 00 // Store 0.009 to R00
005: CLα // clear alpha registry
00: DBLON // turn double mode on for more than 8 letters stored in single number
// ASCII codes: q(81),k(75),h(72),u(85),B(66),Pe(80/69),Pw(80/87)),re(82/69),rw(82/87)
// create the number 0.8175728566800069800087820069820087 for ASCII
// an extra 00 after 80, and 82 used to tell the program subfunction, that there are two letters for // that variable
00: #087
00: SDR 003
00: #20

00: CLα // clear alpha registry

Since to put such a long number takes so many steps, is this really more efficient, than just using f-alpha-Enter? (for variable prompts?) if this long number could be entered in 1 or 2 steps it seems that it would be good.
