ArrayElementByIndex¶

Include: Use System\Reflection.pkg

Purpose¶

Returns an array element by zero-based index.

Syntax¶

Function ArrayElementByIndex Global Variant vArray Integer iIndex Returns Variant

Arguments¶

vArray : Array value to read.

iIndex : Zero-based element index.

Returns¶

The selected array element as a Variant.

Behavior¶

Wrong value types, fixed-array indexes outside the declared size, and overreach cases raise a DataFlex error. Nested struct or array elements are returned as Variant values.

Example¶

String[] asNames
Integer iSize
Variant vName

Move "Ada" to asNames[0]
Get ArrayInstanceSize asNames to iSize
Get ArrayElementByIndex asNames 0 to vName
Send SetArrayElementByIndex (&asNames) 0 "Grace"
