Input CAS var on HP Prime



#4

Why it's not possible to request a CAS var in a program on HP Prime ?
INPUT( only accepts numerical var :(


#5

" INPUT( only accepts numerical var :( "

You can enter alpha value between ""


#6

and how to tranform it into an algebric expression ?
EXPR("4*X+1") just calculates the expression with the X value.
Impossible to work and use CAS commands with the expression 4*X+1 in a program :(
