    One of my value file (eg: file no. 1) is using the Enciphered mode for my communication setting and key 13 for read & write access. Now i would like to credit to the file as mentioned, however, the response code returned was 90 1E. May I know what's the data section in my credit command for the above file setting? I have searched through all the relevant document but couldn't find any hint.

    Thank you.

    Hi Veng,

    Sorry for the later answer.

    For increasing a value, you can use Credit and LimitedCredit. You can split the level of access into two keys. One key allows LimitedCredit (W) and another allows Credit (R&W).

    Can you please give more details of which keys and which settings do you use?

    Actually my main issue is that when I use the encipher mode for communication setting in my file, i couldn't credit to my value file. When i use the plain mode for communication setting, i can successfully credit into my value file. I dont know what's the issue.
