 BLINKER EXECUTABLE SERIAL
------------------------------------------------------------------------------
 Purpose:
 Specify a serial number to encrypt into the .EXE.

 Syntax:
 BLINKER EXECUTABLE SERIAL <cSerialNumber>

 Default:
 None.

 Description:
 This command is used to encrypt a serial number and other information of
 up to 100 characters into the executable file which can then be examined
 by the program using the BLISERNUM() function at runtime.

 This information is encrypted into the executable file and can be used to
 hide a serial number and licensee name in the executable file as a form of
 copy protection. Any information following the BLINKER EXECUTABLE SERIAL
 command on the same line of the script file is encrypted into the .EXE file
 up to a limit of 100 characters. An identical string is returned in the same
 format by the BLISERNUM() function at run time.

 The serial number in the above example can be examined by assigning the
 serial number to a string and then manipulating it using a substring
 function, for example:

 TMPSTRVAR = BLISERNUM()
 ? "Serial number :", SUBSTR(TMPSTRVAR,1,8)
 ? "Number of users :", VAL(SUBSTR(TMPSTRVAR,10,1))
 ? "Licensed to :", SUBSTR(TMPSTRVAR,12,20)

 Example:
 BLINKER EXECUTABLE SERIAL 001001 5 Blink, Inc.
