3-2 Storing Data into Variables
In ALG mode, you can store an expression into a variable; in this case, the value of
the expression is stored in the variable rather than the expression itself.
Example:
Each pink letter is associated with a key and a unique variable. (The A..Z
annunciator in the display confirms this.)
Note that the variables, X, Y, Z and T are different storage locations from the X–
register, Y–register, Z–register, and T–register in the stack.
Storing and Recalling Numbers
Numbers and vectors are stored into, and recalled from, lettered variables by
means of the Store (
) and Recall () commands. Numbers may be
real or complex, decimal or fraction, base 10 or other as supported by the HP 35s.
To store a copy of a displayed number (X–register) to a direct variable:
Press
letter–key
.
To recall a copy of a number from a direct variable to the display:
Press
letter–key .
Example: Storing Numbers.
Store Avogadro's number (approximately 6.0221 × 10
23
) in A.
Keys: Display: Description:
Enter the expression, then
proceed as in the previous
example.
