Scripts - Workspace variables

The value of a workspace variable is not stored in the spreadsheet, but in a separate memory space.

A new workspace variable is created by assigning a value to a valid variable name.

A variable name must adhere to the following rules:

it cannot be longer than 32 characters.
it cannot contain a space or a character from the reserved character set:
```
- + / * = < > # & @ $ | ^ : , ; . ( ) ' " [ ] { }
```
it cannot be equal to a spreadsheet cell address (such as A1 or DC12),
it cannot be equal to a script command or language construct such as beep, print, etc., see List of script commands and language constructs.
variable names are not case sensitive (for example VARX or varx refer to the same variable)

A value is assigned to a variable using the = operator.

The following script code creates a variable sum and assigns the value 11 to it:

sum=5+6;

Workspace variables are untyped and may contain numeric values, strings, complex numbers, matrices, or tables.

num=5;
str="A string is placed in double quotes";
nstr='or single quotes';
cmplx=5+3i;
mtrx={5,6,3|1,8,9};

Clear mem command

The Clear mem command deletes or clears all workspace variables.

When this command is given in the beginning of a script, it deletes all workspace variables.
When this command is given after a workspace variable has already been referenced in the script, it will only clear all workspace variables.
