Example
// Was the element found in the memory zone named "MemoryZone"?
ResFound = MemFound("MemoryZone")
Syntax
<Result> = MemFound(<Memory zone>)
<Result>: Boolean
  • True if the element was found,
  • False otherwise.
<Memory zone>: Character string (with quotes)
Name of the memory zone, defined by MemCreate.
Remarks

Call to MemFound

MemFound must be called after MemSeek, MemFirst, MemLast, MemPrevious and MemNext.

Checks

MemFound cannot be used to perform a check several times in a row. For example, MemFound cannot be used as follows:
MemSeek("DayZone", SoughtValue)
WHILE MemFound("DayZone") = True
MemNext("DayZone")
END
Indeed, the searches performed in a memory zone are exact-match searches. In this case, MemFound and MemOut have the same behavior.
In our example, MemFound returns False (the end of the memory zone is not reached). The following searches will not be performed.

Existence of memory zone

The existence of the memory zone is not checked.
If the specified memory zone does not exist, a WLanguage error occurs when MemFound is used.
To check the existence of a memory zone, use MemExist.
