How to enter a variable in an INPUT ?
Hello, I bought an HP Prime there is very little time!
I wanted to test the HP Prime Basic language by doing a vector product calculation program. The problem is that I can not at all include variables in INPUT (I wish I could enter 4x for example instead of 4) Code: EXPORT Produit_Vectoriel() BEGIN LOCAL A,B,C,D,E,F; LOCAL X,Y,Z,N; INPUT({A,B,C},"Vecteur 1",{"X = ","Y = ","Z = "}); INPUT({D,E,F},"Vecteur 2",{"X' = ","Y' = ","Z' = "}); CAS("B*F*C*E▶X"); C*DA*F▶Y; A*EB*D▶Z; CAS("sqrt(X^2+Y^2+Z^2)▶N"); PRINT(); PRINT(" "); PRINT(" Résultat :"); PRINT(" "+X); PRINT(" "+Y); PRINT(" "+Z); PRINT(" "); PRINT(" Norme : "+N); END; Thank you

If you do input as a string you can use the EXPR() command
EXPR("4*X");

In fact, my program works, I would just like to know how to integrate variables into the calculation (i don't know if that's the good method)

here is an example that worked for me to input a formula with variables in the input command:
INPUT({X,{FF,[8]}}); Y:=EVAL(FF); If that is your question

That was just example of how to do the input statement to accept a string, your variables maybe different
