I programmed an Excel spreadsheet (in VBA) to calculate pressure drop (Beggs Brill/Modified Hagedorn and Brown Method (With Griffith Correlation)) and I remember counting more than 100 variables and 17 sub-functions.

I'd say that a calculator may not be the right tool for this, and you should better stick to Excel or another program that suits this application even better.

If you still want to use the 34s for this, here is a much shorter input routine that does not require separate prompts for each and every single variable (and thus 26x5 = 130 steps for A...Z):

Code:
#026
SDR 003
INC X
STO 00
CLα
#064
RCL+00
x→α
α"=?"
R↓
RCL→00
PROMPT
STO→00
ISG 00
BACK 010

Note: if you're not yet familiar with the 34s, the first three lines are just a fancy way of writing 1,026. ;-)
The routine may be updated for more than 26 variables, for instance by calling them ...X, Y, Z, A2, B2, C2, ...
Or switch to lower case: X, Y, Z, a, b, c, ...
