Descrição:

SEND sends data either to a terminal, or on an advanced program-to-program communications (APPC) mapped conversation.
The form of SEND command that is described here is used for sending data to a terminal.
For details of the SEND command for use on APPC mapped conversations, see SEND (APPC).
An APPC conversation allows a program to send data to, and receive data from, a program that is running in a remote system.
Programming that uses APPC conversations is called Distributed Transaction Programming (DTP).
For guidance information about DTP, refer to the TXSeries for Multiplatforms Intercommunication Guide.

Opções:

CTLCHAR(data-value)
• Specifies a one-byte Write Control Character (WCC) that controls the SEND command.
• A COBOL user must specify a data area that contains this character.
• If the option is omitted from the SEND command, all Modified Data Tags are reset to zero and the keyboard is restored.

ERASE
• Specifies that the screen is to be erased and the cursor returned to the upper left corner of the screen before writing occurs.
• ERASE should be specified in the first output command of a transaction or in a series of pseudoconversational transactions.
• This clears the screen ready for the new output data.

FLENGTH(data-value)
• A 32-bit alternative to LENGTH(data-value).

FROM(data-area)
• Specifies the data that is to be written to the terminal.

LENGTH(data-value)
• Specifies, as a 16-bit binary value, the length of the data that is to be written.
• See LENGTH for more information about using this option.

WAIT
• Specifies that processing of the command must be completed before any subsequent processing is attempted.
• If the WAIT option is not specified, control is returned to the application program after processing of the command has started.
• A subsequent input or output request (terminal control or Basic Mapping Support (BMS)) to the terminal that is associated with the task causes the application program to wait until the previous request has been completed.

Condições:

INVREQ
• Occurs for the following conditions, depending on the options that are specified on the SEND command:
  • Any of the terminal-related SEND options (ERASE or CTLCHAR) has been specified, but the principal facility for the task is not a terminal (that is, it is an APPC conversation).
  • An attempt is made to issue a SEND command with terminal-related options from a remotely linked-to program.
  • A remotely linked-to program attempted to execute a SEND command that refers to the principal facility.
• Ação pré-definida: Terminates the task abnormally.

LENGERR
• Occurs if an out-of-range value is supplied in the LENGTH or FLENGTH option (zero is acceptable).
• Ação pré-definida: Terminates the task abnormally.

NOTALLOC
• Occurs if this command is issued in a task that is not associated with a terminal.
• Ação pré-definida: Terminates the task abnormally.

TERMERR
• Occurs if a terminal-related error occurs.
• Ação pré-definida: Terminate the task abnormally (with abend code ATNI).
