Calculates pressure change of the
gas when temperature drops from
297.1 K to 287.1 K (negative
result indicates drop in pressure).
Using SOLVE in Program
You can use the SOLVE operation as part of a program.
If appropriate, include or prompt for initial guesses (into the unknown
variable and into the X–register) before executing the SOLVE variable
instruction. The two instructions for solving an equation for an unknown
variable appear in programs as:
/
label
#
variable
The programmed SOLVE instruction does not produce a labeled display
(variable = value) since this might not be the significant output for your
program (that is, you might wart to do further calculations with this number
