Syntax
<Result> = MemSeek(<Name of Memory Zone> , <Sought Value> [, <Element>])
<Result>: Any type
  • If <Element> is set to True (by default):
    • Value of the first element found,
    • Empty string ("") if no element was found.

    • Subscript of the first element found,
    • -1 if no element was found.
<Name of Memory Zone>: Character string (with quotes)
Name of the memory zone, defined by MemCreate.
<Sought Value>: Character string (with quotes)
Value sought in the memory zone. When the search is performed on the added value, this value and the value added by MemAdd must have the same type.

  • False: the search is performed according to the return value.
Remarks

Browsing a memory zone

MemSeek is used to start browsing the memory zone.
Once MemSeek has been run:
  • MemNext will be positioned on the next element sought.
  • MemPrevious will be positioned on the previous element sought.
To resume a standard browse, you must use MemFirst or MemLast.

Error

A WLanguage error occurs when MemSeek is run:
  • if <Name of Memory Zone> does not exist. To check the existence of a memory zone, use MemExist.
  • if <Name of Memory Zone> was not sorted beforehand. To sort a memory zone, use MemSort.
