Attention

Handle and remember the encryption key for encryption/decrypting with care. If you forget the key, decryption cannot be done.
For command "On" and "Off," variables cannot be used.
When encrypting the TP panel file, make sure that the reserved area of the Panel Designer is not included in area to be encrypted.
If the reserved area of Panel Designer is included in the encryption area, an execution error will occur in the TP panel after encryption.
In addition, the TP panel editor will not be able to recognize files properly.
The reserved area for the Panel Designer is shown as follows.

#ifdef TP_DESIGNER
'<<--TPDESIGNER_RESERVED-->>
     
     
:
     
'<<--TPDESIGNER_RESERVED-->>
#endif
