di_READ()
Replacement READ command issues a read/submit to multiple device types
------------------------------------------------------------------------------
Syntax

    di_READ([<cMethod>],[<cAction>],[<cCaption>]) --> nSuccessList

Arguments

    <cMethod> is the HTML Form method, i.e. POST/GET

    <cAction> is the URL of CGI, i.e. http://myhost.com/cgi-bin/myapp

    <cCaption> is the caption to appear on the HTML "submit" button

Returns

    nSuccessList is the sum of the devices handles successfully
    written to.  Only devices currently set to output are addressed;
    therefore, nSuccessList is always less than or equal to the current
    return value from di_setOutput().

Description

    Issues a READ to all devices enabled for output and returns a list
    of devices successfully implementing the READ.  For the screen
    device, use a standard READ; for HTML devices create a FORM around
    the GETLIST.  Specification of the METHOD, ACTION and submit CAPTION
    can be optionally specified as arguments for output to HTML devices.
    Other devices disregard the arguments.
