RecNum
RecNum
The RecNum instruction finds the number of records in an array of structures to the end data.
* If you omit the input parameter, the default value is not applied. A building error will occur.
The RecNum instruction searches from the start of an array In[] (whose elements are structures). The
instruction searches for elements for which the value of member to process Member matches end data
EndDat. As the result, it assigns the number of elements (records) up to the element just before the ele-
ment with an EndDat match to Out. One of the members to process in the elements of In[] is passed as
an argument to Member.
Always attach the element number to input parameter that is passed to In[], e.g., array[3].
