<Result> = MemNext(<Memory area>)
<Result>: Any type - If next element exists: return value of next element, defined by functions MemAdd or MemModify.
- If the following element does not exist: an empty string ("").
<Memory area>: Character string Name of the memory area, defined by MemCreate. Remarks The sorts performed by MemSort are taken into account during the call to MemNext. If no sort was requested, MemNext returns the value of the next element according to the order of the elements added by MemAdd. Existence of memory area The existence of the memory area is not checked. If the specified memory area does not exist, a WLanguage error occurs when MemNext is used. To check the existence of a memory area, use MemExist. Performing a search in a memory area If MemSeek is used before the call to MemNext, MemNext will be positioned on the next element sought. Equivalence The two following syntaxes are equivalent: Res = MemNext(<Memory area>)
Res = MemRetrieve(<Memory area>, MemCurrent(<Memory area>)+1) Business / UI classification: Neutral code
