RWA_IMAGE_ANCHOR

Purpose

Creates an anchor for up to three different images in a single position. For example, it could be used to display a button that changes colour when the mouse hovers above it, then changes colour again when you click it - that is, three different images of the button are displayed showing it in three different colours. This subroutine appends the code generated to a string.

Syntax

RWA_IMAGE_ANCHOR(vString, LinkURL, Description, aImageURLArray, TargetFrame, aClass)

Parameters

vString A variable containing the string to which the generated code is appended. On return, the variable contains the modified string. If the string does not exist, it is created.
