SPECIFYING PRINT AND TRANSFER OPERATIONS

J.5.1. Peripheral Operations

The (**PRINT*) and (**XFER**) fields specify the peripheral operations to be performed on data when the PRINT or XFER key is pressed, and initiate transfer of this data. On the basic UTS 30, the data can only be transferred to the printer; on the programmable version, data can be transferred to either diskette subsystem or printer.

These fields are accessible to both the host and the terminal operator. The formats and functions of the two fields are similar; the significant difference is that when the (**XFER**) field is used, the FCCs are transmitted and can be printed.

Below the (**XFER**) protected labels are three subfields: (from/to/function). These subfields are used for peripheral device information, as follows:

The "from" subfield specifies the device from which data is to be obtained (for example, from D2).

The "to" subfield defines the peripheral device to which the data will be sent. In the case of the UTS 30 basic version, this is the printer; in the case of the UTS 30 programmable version, this may be the printer or diskette subsystems.

The "function" subfield specifies the type of activity to be performed (for example, write).

Entries allowed in the subfields are defined in Tables J-5 and J-6.

Table J-5. Entries in the uFrom" and '7o" Subfields of the (**PRINT*) and (**XFER**) Fields

Entry Meaning

P1 or PR Designates the printer attached to the programmable UTS 30.

01 to 04 Designates a specific diskette drive attached to the programmable UTS 30.

Note: The identifiers for the primary diskette subsystem are 01 for the left drive and 02 for the right drive. Identifiers for the secondary diskette subsystem are 03 for the left drive and 04 for the right drive. If either diskette subsystem has only one drive, the identifiers are assigned consecutive numbers, ignoring the empty space. Thus, if the primary diskette subsystem has only one drive, it will be 01 and the two drives in the secondary subsystem will be 02 and 03.

J-12

Table J-6. Entries in the "Function" Subfield of the (**PRINT*) and (**XFER**) Fields

Designates the autotransmit function. Successive blocks of data are displayed and transferred without operator intervention. The transmit mode specified in the XMIT( ) field defines the format in which the data will be transmitted.

Designates the copy function. This operation inputs data to the screen from the diskette specified in the "from" subfield, and then outputs through the screen to the device specified in the "to" subfield. This process continues until the input device reaches the address previously entered by the operator in the SEARCH( ) field, until the operation is manually terminated, or until the end of media occurs.

Designates the edit function. This operation is similar to the copy function except that the operator first has the chance to change each screen of data before it is passed to the device identified in the "to" subfield. This process continues until the input device reaches the address previously entered by the operator in the SEARCH( ) field, until the operation is manually terminated, or until the end of media occurs.

Designates the home function. The device specified in the "from" subfield will search to the starting address (home position) when the PRINT or XFER key is pressed.

Designates the read function. The diskette drive specified in the "from" subfield reads and inputs one screen of data each time the operator presses the PRINT or XFER key, as applicable.

Copy diskette. Designed for copying the system diskette. All information on the diskette designated in the "fr" field is copied to the diskette designated in the "to" field. No "file open"

command is needed.

J.5.2. Format of Print and Transfer Operations

J.5.2.1. PRNT( ) Field

This 4-character field specifies the format of the print function to be performed when the PRINT key is pressed. Allowable entries are listed in Table J-7. These functions apply only to the write, copy, and edit entries in the (**PRINT*) field. All data from the home position or from the last SOE position through the cursor position is printed. FCCs are not included.

J.5.2.2. XFER( ) Field

SPERRY UTS 30 SINGLE STATION

System Reference J-13

The entry in this 4-character field specifies the format of the transfer function that will be performed by the UTS 30 when the XFER key is pressed. For each entry, data on the screen from the home position (or from the last SOE position) through the cursor location, plus any included FCCs, is transferred. Spaces at the ends of lines and cursor returns (CR) are suppressed.

The entries are listed in Table J-8. This field applies only to the write, copy, and edit entries in the (**XFER**) field.

J.5.2.3. XMIT( ) Field

This 4-character field specifies the type of online transmission that will be performed when the XMIT key is pressed. These are the same entries and the same functions defined for the XFER( ) field. See Table J-8.

Table J-8. Entries in the XFER( ) and XMIT( ) Fields

Entry Meaning

ALL Causes all data and FCCs from home position or the last SOE through the cursor position to be transferred.

VAR Causes only unprotected data and FCCs to be transferred. This is the default condition.

CHAN Causes only FCC fields that have been changed, as indicated by the internal changed-field indicators, to be transferred.
