~ used in the generation of other records unless it is also stored in one of the propammer-accessible areas, such as the Special Storage, Inqwry Buffer, and card input/output buffer
areas.
Auxilialy card files can be used in conjunction with the generation of a data record, but t"de-oriented processing nonnal to data processing functions is just not possible the way the terminal master control program is laid out now. This is not so much a deficiency as an important consideration in evaluating how the 3735 can help you implement your overall data processing functions.Three basic trPes of operations can be performed on data:
validation, anthmetic, and editing.
Data fields can be checked for type (alphanumeric, alpha-betic, or numeric), length (maximum, minimum, or exact), value (greater than, less than, or equal to one or more constants), and/or self-check (modulo 10 or 11). A data field can be specified as optional, which suspends the checks if the operator skips the field. Batch numbers can be assigned, permitting accumulation of batch totals; up to 128 different batches can be identified.
Arithmetic operations are performed with the counters;
two counters or one counter and another storage area can be involved. Clearing, addition, subtraction, multiplication, division (with or without rounding), and comparison operations are provided.
A wide range of edit options is provided. Description of numeric fields is COBOL-like. Zero suppression with blank or asterisk fill, Doating dollar and arithmetic ~s (Plus and minus), and CR (credit)/DB (debit) insertions can be specit"aed. Fields to be printed can be centered, right-justit"aed with blank or zero fill, underlined, or printed with the numeric editing specifications. Output to the Inquiry Buffer and Special ~torage areas can be right-justified with zero or blank fills.
Each field that goes into the data record can be suppressed from printing and/or transmission if desired.
Specification of the processing operation for a particular form should be relatively simple. Typically, the user creates a specitlcation in a format simDar to the macro-language actually used. Fields are identified by name (including counters) and by position within the storage area (ex-cludiJig counters, of course).
These specit"lCations are converted into macro-language by the programmer, using IBM System/360 Assembly language supplemented with extensive macros. After assembly, another p~ (Form Description Utility) formats the resulting object program for transmission to a terminal.
Libraries of FDPs can be maintained at the computer site.
The terminals do not have to receive the same set of programs.
The 3735 is supported under DOS BTAM, under DOS/VS BTAM and VTAM, under OS BTAM and TCAM, and under OS/VS BTAM, TCAM, and VTAM. Under Os, a 128K Model 40 is required for program generation. Under DOS, a 16K Model 2S can handle the program generation-but keep in mind that 32K bytes of storage are required for telecommunications under DOS.
COMPONENTS
DISK STORAGE: The basic disk unit includes 45.2K bytes for storage of the Terminal Control Program and 62.8K bytes for storage of user FDPs and data records. The basic disk storage capacity can be expanded by one or ~o
additional increments of 41.8K bytes each plus a third increment of 167.5K bytes to provide a maximum total storage capacity of 314.1K bytes. Disk storage is reduced by 1.9K bytes when the optional 3286 Model 3 Printer and/or Operator ID Card Reader is added, by 3.8K bytes when the optional File Storage Capability is added, by 5.7K bytes when all of the above are added, and by 7.6K bytes when the optional Buffer E~ansion is added by itself or in combination with the preceding three options.
The disk is organized in sectors of 4fJ) bytes each. Four identit"lC8tion bytes are required for each data record, so each data record can be up to 476 bytes long, including t"Jeld and record delimiters but not communications line control characters.
IBM estimates that a typical FDP requires about 1000 bytes of storage. However, when FDPs are stored, half of each sector is left unused. Therefore, a typical PDP wDl probably take four sectors.
KEYBOARD/PRINTER: The Selectric I/O II keyboard/
printer is based on the familiar Selectric Typewriter, with . .

~ keyboard and printing functions logically separated. When typing automatically (called power typing by IBM), the Selectric runs at 15.5 characters per second. Character spaCing is 10 characters per inch (Pica), and vertical spacing is 6 lines per inch.
The basic machine is equipped with friction-feed forms movement, like a conventional typewriter. The maximum line width is 130 characters (13 inches). Optionally, the printer can be equipped with pin-feed forms movement. A wide selection of sizes is available, ranging from S-3/4-inch form width (4-5/8 writing width) to 13-S/S-inch form width (12-1/2 writing width). IBM does not currently offer a split platen, two-color ribbon, or front-feed forms capability for the Selectric printer.
The keyboard contains many controls and indicators (lights) in addition to the alphanumeric keys. On the right-hand side of the character keyboard, a IO-key numeric pad has been overlaid (effectively a third shift) to facilitate the entry of numeric items; the layout conforms to a

3286 MODEL 3 PRINTER: This optional unit prints via the matrix technique at a rated speed of 66 char/second.
The printer is available with 120, 126, or 132 print positions and forms each character of the standard 64-character set of EBCDIC or ASCII symbols via a 4-by-7 dot matrix. It accommodates six-part continuous, pin-fed forms. The 3286 Model 3 is unbuffered.
5496 DATA RECORDER: This optional unit provides input and output via 96-column punched cards. It is a keypunch that operates at 20 columns per second (60 cps) on line. It can be used off-line like a normal keypunch.
