Background
2.8.5.1.1 (01-02-2024) Background As a result of a study, it was concluded that Examination had a need for a new information management system. The study group recommended a terminal assisted Audit Information Management System (AIMS). A stand alone direct access terminal system was considered along with the enhancement of IDRS. Enhancement of IDRS was determined to be clearly the best choice for the Service. This new system satisfied Examination Division's current needs for accurate and timely inventory controls, better control of assessments and up-to-date management reports. The system traces examination results through final determination of tax liability including Appeals and Tax Court. After the successful implementation of AIMS for the Examination Division, control of returns in Appeals was added to AIMS. As of January 1, 1977 control of Exempt Organization returns was added and on October 1, 1977 control of Employee Plan returns was added.

Exhibit 2.8.5-6 Command Code AMSOC a) Batching is done in groups of one to 100 documents for short closings. Line 1 of the input screen is to be used to input data which refers to the entire block. b) Computer Action for Batch Input the computer will perform validity checks between items for input for line 1 and lines 2–23. Each line beginning with line 2 is to be considered an individual entry, a maximum entry input per page will be 22 documents, to include line 2 thru 23. Line 24 is reserved for operational messages. c) In the following display the five closings may be entered on one page Title: Batch Input Display - Sample Input. Description: Represents a screen shot showing the input of CC AMSOC for the non-examined closing of 5 different tax modules. Line 1 begins with AMSOC followed by the BATCH-IND "L", followed by the BLOCK-NUM "100", followed by TERMINAL-SEQUENCE-NUM "1001", each item being separated by a single space. Lines 2 through 6 consist of the TIN, followed by the TAX-PERIOD, followed by the NAME-CONTROL, followed by the DISPOSAL-CODE. Each element is separated by space. Each TIN is different. Line 4 shows spaces for the TAX-PERIOD and DISP-CD. Line 5 shows spaces for the TAX-PERIOD. The use of spaces for these elements would mean that the TAX-PERIOD or DISP-CD from the previous line shall be used. Please click here for the text description of the image. a. For NMF cases the "L" in position 7, line 1 indicates that the last closing in the block is on this page (in this case line 6) 1. Where the tax period or disposal code is blank, it is assumed to be the same as the previous line. For instance, in the input display, lines 4 and 5 are tax period 197412 and line 4 would be assumed to have a disposal code 21. 2. When an entire block (more than 22 closings) cannot be entered on one page the "Batch Position Indicator" "L" will not be entered in line 1 of that page and the terminal operator will input the entry code and proceed to the next page by depressing the "Enter" key and omitting the MFT and blocking series from line 1 of the next page. When the last entry for the batch has been entered on the screen, the terminal operator will then enter the literal "L" in the seventh position of line 1, input entry code and depress the "Enter" key. 3. When the literal 'R' is entered in the first position of any batch line 3–23 the TIN, Disposal Code, and Name Control entered on the previous line is repeated for the current line if those fields are left blank. For example, if an 'R' is entered in position 1 and positions 21–24 (name control) is left blank the name control from the previous line will be issued. If position 21–24 is not left blank whatever value is entered will be used whether or not there is an 'R' in the first position of the line.
