Erases a variable so memory will be released.









The name of the variable to erase.


The variable must be dimensioned before you can erase it.


When you need temporary variables you can erase them after you used them. This way your program uses less memory.


You can only ERASE the last dimensioned variables. So when you DIM 2 variables for local purposes, you must ERASE these variables. The order in which you ERASE them doesn't matter.


For example :

Dim a1 as byte , a2 as byte , a3 as byte , a4 as byte

'use the vars

ERASE a3 : ERASE a4          'erase the last 2 vars because they were temp vars

Dim a5 as Byte 'Dim new var

Now you can't erase the vars a1 and a2 anymore !


Note that ERASED variables don't show up in the report file nor in the simulator.




Dim A As Byte                           'DIM variable

A = 255                                   'assign value

Print A                                   'PRINT variable

Erase A                                   'ERASE

Dim A As Integer                         'DIM again but now as INT

Print A                                   'PRINT again

REM Note that A uses the same space a the previous ERASED var A so

REM it still holds the value of the previous assigned variable
