how to assign default value to a parameter

I need to set a default value to the the following parameters in my SQL query so that I do not have to pass them in via a form.
@gbloptState AS VARCHAR(4) ,   = 4-
@InsPrfCrdLtrOpt AS VARCHAR(1) = 1

Just set the value that you want in the parameter definition:

ALTER PROCEDURE [dbo].[InsProfile_CredLetter_Parm]
     (
       @gbloptState AS VARCHAR(4)  = '4',
       @InsPrfCrdLtrOpt AS VARCHAR(1) = '1'

.
