This is an example of command code ACTON. ACTON is used to establish, update, close control bases, correct name controls on dummy accounts, and enter history items on IDRS modules. A valid input of CC ENMOD, SUMRY, TXMOD, PLAGD, ADJ54, FRM49, FRM77, STAUP, DRT24, DRT48, ACTON, or REINF must precede each ACTON input request. The following exhibits gives the Tax Examiners the Procedures on how to use IDRS Command Code ACTON. The case status codes are A=Assigned, B=Background, C=Closed, M=Monitor/Other, S=Suspense. To record a history item, input the following: ACTON 30 20712 (new line) H, letter12C. When a SUMRY request indicates that a memo account is present on the file indicating that the account has been resequenced to another TIN, use caution when establishing a new control base on any module within the account.
