Syntax

MemCreate(<Memory area>)

<Memory area>: Character string

Name of the memory area to create (up to 20 characters). This name will be used by all the functions for managing memory areas.

Remarks

Existence of memory area

The existence of the memory area is not checked. If the memory area already existed, this memory area is overwritten. To check the existence of a memory area, use MemExist.

Automatic completion on the name of memory area

In the code editor, as soon as a memory area has been manipulated with a Memxxx function (for example the MemCreatefunction), this name will be automatically proposed when entering WLanguage functions that accept the name of the memory area as a parameter.

Size of information

If the size of the information to store in the memory area is greater than the available memory space, a "swap disk" is used: one or more temporary files are created in order to store the additional information. These temporary files are created on the local disk, in the directory specified by the "TEMP" environment variable.
