ASize()

 

ASIZE()

Adjust the size of an array

Syntax

      ASIZE(<aArray>, <nLen>) --> aTarget

Arguments

<aArray> Name of array to be dynamically altered

<nLen> Numeric value representing the new size of <aArray>

Returns

<aTarget> an array pointer reference to <aTarget>.

Description

This function will dynamically increase or decrease the size of <aArray> by adjusting the length of the array to <nLen> subscript positions.

If the length of the array <aArray> is shortened, those former subscript positions are lost. If the length of the array is lengthened a NIL value is assigned to the new subscript position.

Examples

      LOCAL aArray := { 1 }      // Result: aArray is { 1 }
      ASize( aArray, 3 )         // Result: aArray is { 1, NIL, NIL }
      ASize( aArray, 1 )         // Result: aArray is { 1 }

Compliance

If HB_COMPAT_C53 is defined, the function generates an Error, else it will return the array itself.
