6-3-1 Exponential
Description
Mathematical function to calculate a value raised to a power.
Syntax
result = Exp (value, exponent)
Remarks
Typical Example
MSBMask = Exp (2, 15)
In this example, 'MSBMask' is assigned the value 215, i.e. 32,768.
6-3-2 PlayOLE
Description
Initiate an OLE verb or 'method' on an OLE 2 object. The verb number is
object dependent so refer to the object's documentation. This function is now
largely obsolete as most objects are nowadays ActiveX objects.
Syntax
returnstate = PlayOLE("objectname",OLEVerbNumber)
Remarks
Argument Type Description
result integer Point name to receive returned result of value
raised to the power of exponent.
value integer Number to raise.
exponent integer Power to raise value by.
Argument Type Description
returnstate bool Returnstate is '1' if the function is successful, or
'0' otherwise.
objectname string The identifier of the OLE object to be played.
OLEVerbNumber integer The verb number has a specific meaning to the
OLE application. Typical values are:
0: specifies the action that occurs when an
end-user double clicks the object in its
container. The object determines this action
(often 'edit' or 'play').
-1: instructs the object to show itself for editing
or viewing. Usually an alias for some other
object-defined verb.
-2: instructs an object to open itself for editing
in a window separate from that of its container.
-3: causes an object to remove its user
interface from the view. Applies only to objects
that are activated in-place.
Positive numbers designate object specific
verbs.
