VarArrayGet

Get a value from a single cell of a variant array

Declaration

Source position: varianth.inc line 376

function VarArrayGet(

const A: Variant;

const Indices: array of LongInt

):Variant;

VarArrayGet returns the value in the variant array A at the location indicated by Indices. Thus the statement

B:=VarArrayGet(A,[2,1]);

is equivalent to

B:=A[2,1];

The difference is that the previous is usable when the amount of indices is not known at compile time.

If the number of indices is wrong (or out of range) an exception may be raised.
