# #MaxMem

Sets the maximum capacity of each variable to the specified number of megabytes.

    #MaxMem Megabytes

### Parameters

Megabytes | The number of megabytes to allow for each variable. A value larger than 4095 is considered to be 4095. A value less than 1 is considered to be 1.

### Remarks

If this directive is unspecified in the script, it will behave as though set to 64.

The purpose of limiting each variable's capacity is to prevent a buggy script from consuming all available system memory. Raising or lowering the limit does not affect the performance of a script, nor does it change how much memory the script actually uses (except in the case of WinGetText and ControlGetText, which will be capable of retrieving more text if #MaxMem is increased).

This setting is global, meaning that it needs to be specified only once (anywhere in the script) to affect the behavior of the entire script.

This setting restricts only the automatic expansion that a variable does on its own. It does not affect VarSetCapacity.
