No.

When  the  value  of  a data parameter being passed to  a
called product is always  the  name  of  the  record  group
defined in the current form. Data parameters  are  used  to
pass data to produts invoked with the run_product built-in
subprogram.

Text Parameters
Data Parameters

To  indirectly  reference  a  parameter use the NAME IN,
COPY 'built-ins to indirectly   set  and  reference  the 
parameters  value'  Example  name_in ('capital parameter my
param'), Copy ('NAME','Parameter my_param')

In  Pl/Sql,  You  can reference and set the values of form
parameters using bind  variables syntax. Ex. PARAMETER  name
= '' or :block.item = PARAMETER 
Parameter name

Run_product is a built-in, Used to invoke one of the
supported oracle tools products and specifies the name of
the document or module to be run. If the called product is
unavailable at the time of the call, Oracle Forms returns a
message to the opertor.

The  maximum  no  of  chars  the parameter can store is only
valid for char parameters,  which  can  be  upto 64K. No
parameters default to 23Bytes and Date parameter default to
7Bytes.

You  can  pass  parameter values to a form when an
application executes the call_form, New_form, Open_form or
Run_product.

For Preparing parameters to be passed, we can use the 
following built-ins 

CREATE_PARAMETER_LIST :- Creates Parameter list
ADD_PARAMETER :-Adds a parameter to parameter list
DELETE_PARAMETER
DELETE_PARAMETER_LIST

Parameters  provide  a simple mechanism for defining and
setting the values of  inputs  that  are  required  by  a
form at startup. Form parameters are variables of type
char,number,date that you define at design time.
