freeBytes()

Syntax

    the freeBytes

Description

Function; indicates the total number of bytes of free memory, which may not be contiguous. A kilobyte (K) is 1024 bytes. A megabyte (MB) is 1024 kilobytes.

This function differs from `freeBlock` in that it reports all free memory, not just contiguous memory.

On the Macintosh, selecting Use System Temporary Memory in the Director General Preferences or in a projector's Options dialog box tells the `freeBytes` function to return all the free memory that is available to the application. This amount equals the application's allocation shown in its Get Info dialog box and the Largest Unused Block value in the About This Macintosh dialog box.

Example

This statement checks whether more than 200K of memory is available and plays a color movie if it is:

    if (the freeBytes > (200 * 1024)) then play movie "colorMovie"
