To Perform Symbolic Calculations
If you want a function or program to perform symbolic calculations, you must use a
global variable instead of a local. However, you must be certain that the global variable
does not already exist outside of the program. The following methods can help.
•
Refer to a global variable name, typically with two or more characters, that is not
likely to exist outside of the function or program.
•
Include
DelVar
within the function or program to delete the global variable, if it exists,
before referring to it. (
DelVar
does not delete locked or archived variables.)

Strings are used to enter and display text characters. You can type a string directly, or
you can store a string to a variable.
