// "MyMemoryZone" will be automatically proposed in the completion
sString is string = "A"
sString = Complete(sString, 10000, "B")
Trace(Length(sString))

MemCreate("MZ")
MemAdd("MZ", "1", sString)

Trace(Length(sString))
Syntax
MemCreate(<Name of Memory Zone>)
<Name of Memory Zone>: Character string (with quotes)
Name of the memory zone to create (up to 20 characters). This name will be used by all the functions for managing memory zones.
Remarks

Existence of memory zone

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

Automatic completion on the name of memory zone

In the code editor, as soon as a memory zone was handled by a Memxxx function (MemCreate for example), this name will be automatically proposed when entering WLanguage functions that accept the name of a memory zone in parameter.

Size of information

If the size of the information to store in the memory zone 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.
