Eq 4 St(
STRNG menu
Eq 4 St( equationVariable , stringVariable )
Converts the contents of equationVariable to a string
and stores it to stringVariable. Be sure to specify an
equation variable, not an equation.
To create an equation variable, use an equal sign (=) to
define the variable. For example, enter
A=B ¹ C , not
B ¹ C ¶ A .
A=B¹C b Done
5¶B b 5
2¶C b 2
A b 10
Eq 4St(A,STR) b Done

Refer to syntax information for Assignment on page 270.
If you use = in an expression in which the first argument
is not a variable name at the beginning of a line, the = is
treated as N(.
Example of = treated as N(, where 4=6+1 is
evaluated as 4 N(6+1):
4=6+1 b L 3
For true/false comparison, use == instead:
4==6+1 b 0
