My wishes about NEW-RPL
sorry for my bad English =[
Hi, HP-RPL users and RPN lovers, Please comment on each point exposed I have not tried yet NEWRPL because I have not a hp50real and the NewRPL-DEMO app for windows not have a keyboard =( these suggestions are based on what has the hp 50 and that I would like to see in newRPL or in a future firmware upgrade from HP 1: Use an operator optional as end line, semicolon (; ) for example. Where the program editor can format each sentences, and thus to adjust the code vertically, my HP48/50 programs always the editor adjusted to line the width of the screen and not as I wrote in the source code =( Code: « 'RCUADRATIC' RCL -> Code: « And not Code: « 3 →LIST { A B C } STO B NEG B 2 ^ 4 A * C * - √ + 2 A * / B NEG B 2 ^ 4 A * C * - √ - 2 A * / { A B C } PURGE ; 2: Do not delete comments to store programs Code: «@ inicio de programa 'RCUADRATIC' RCL -> Code: « 3: use a different delimiter between variables & symbolic expression, for example a polynomial 'x^1' -> 'x' would be treated as algebraic expression and non-variable delimiters `` for storage Code: `RCUADRADIC` STO delimiters '' for algebraic expression Code: 'X' STO Code: 'X^1' EVAL TYPE @ returns 6 should return the same data type (9), the solution to the ambiguity of a variable as algrebaica expression is solved with my idea Code:
Hold right key (hp50)+ [''], put the backtick or reverse quotes 4: use "ENDIF" "ENDCASE" "ENDWHILE" "ENDDO" ETC as option to visually and detect the body block, also this allows easier code converters The following code is very difficult to know which end is up to each block when no indentation Code: IF -> Code: IF 5: A flag to maintain always a complex number in format (x, y) dupla (x, y) [ENTER] (x, y) and not x+y*i and not (r, angle theta) 6: a new type of data is needed tripla (x,y,z) for geometric objects 7: Local storage in RPN Code: « == 1 2 3 `A` `B` `C` → @ RPN NOTATION =) Code: « == 1 2 3 → A B C @ infix notation =( |
