EXEC CICS SEND TEXT
    [RESP(response-code)]
    [RESP2(response-code-2)]
END-EXEC.

Parameters Explained

RESP Parameters

Response codes returned by the command:

  • RESP: Primary response code - indicates the success or failure of the send text operation
  • RESP2: Secondary response code - provides additional error information when RESP indicates failure
  • Always check these codes for command success before proceeding with data processing
  • Handle command failures appropriately to prevent application errors

Send Text Types

1. Basic Send Texts

  • Basic send texts: Standard send text operations that handle simple sending without special formatting
  • Mapped send texts: Send text operations that use predefined field mappings to structure send text data
  • Unmapped send texts: Raw send text operations that handle unstructured sending without predefined field mappings
  • Custom send texts: Specialized send text operations designed for specific application requirements

2. Advanced Send Texts

  • Advanced send texts: Complex send text operations that handle sophisticated sending processing and validation
  • Secure send texts: Send text operations that include encryption and security features for sensitive sending
  • Encrypted send texts: Send text operations that automatically encrypt send text data
  • Compressed send texts: Send text operations that handle compressed sending streams and automatically compress send text data

3. Specialized Send Texts

  • Specialized send texts: Send text operations tailored for specific protocols or communication methods
  • High-performance send texts: Optimized send text operations designed for maximum throughput and efficiency
  • Low-latency send texts: Send text operations optimized for minimal delay and real-time processing requirements
  • High-throughput send texts: Send text operations designed to handle large volumes of sending efficiently

Send Text Processing

1. Send Text Preparation

Send text preparation includes:

  • Send text validation - ensuring the send text operation is properly configured and authorized
  • Send text formatting - preparing data structures and buffers for send text data
  • Send text encoding - setting up proper character encoding and data transformation
  • Send text processing - initializing the send text operation and preparing for sending

2. Send Text Transmission

Send text transmission includes:

  • Send text routing - directing send text data to the appropriate processing location
  • Send text delivery - ensuring send text data reaches the correct destination within the application
  • Transmission confirmation - verifying that send text was completed successfully
  • Error handling - managing transmission failures and implementing retry mechanisms

3. Output Management

Output management includes:

  • User management - handling user sessions and maintaining connection state
  • Output formatting - structuring send text data for presentation or further processing
  • User experience - ensuring smooth data flow and responsive application behavior
  • Performance optimization - maximizing send text efficiency and minimizing resource usage

Common Response Codes

Success Response Codes

  • NORMAL (0): Send text operation completed successfully - sending was completed without errors
  • SEND (4): Send text operation completed - operation completed with send text-specific status

Error Response Codes

  • INVREQ (16): Invalid request - the send text operation parameters are incorrect or unauthorized
  • NOTFND (20): Resource not found - the specified send text resource does not exist
  • LENGERR (22): Length error - the send text data length exceeds expected limits
  • SEND (24): Send text error - a send text-specific error occurred during the operation

Best Practices

1. Send Text Preparation

  • Prepare send text appropriately - ensure all necessary resources and configurations are in place
  • Validate send text content - verify that send text data meets expected format and quality standards
  • Handle different send text types - implement flexible processing to accommodate various sending formats
  • Ensure send text integrity - maintain data consistency and prevent corruption during sending

2. Error Handling

  • Check all response codes - always examine both RESP and RESP2 for complete error information
  • Handle send text failures - implement appropriate recovery mechanisms for failed send text operations
  • Implement retry logic - provide automatic retry capabilities for transient failures
  • Log error conditions - maintain detailed logs for troubleshooting and monitoring purposes

3. Performance Optimization

  • Minimize send text operations - reduce unnecessary send text calls to improve overall performance
  • Use efficient send text formats - choose appropriate data formats to minimize processing overhead
  • Optimize user updates - streamline user interface updates to reduce response time
  • Manage user resources - efficiently allocate and manage system resources for send text operations

Explain It Like I'm 5 Years Old

Imagine you're sending text:

When you want to send text, you write it down and send it. If you send it, it goes to the person. If you don't send it, it stays with you.

CICS SEND TEXT is like sending text. The computer program writes data and sends it. If it sends it, it goes to the right place. If it doesn't send it, it stays with the program.

Just like you send text, the computer program sends text data!

Exercises

Exercise 1: Send Text Operation

Write a CICS SEND TEXT command to perform a send text operation.

EXEC CICS SEND TEXT
    RESP(WS-RESPONSE)
    RESP2(WS-RESPONSE2)
END-EXEC.

Exercise 2: Send Text Processing

How would you implement comprehensive send text processing that handles different send text types and requirements?

Answer: Identify different send text types and appropriate handling, implement send text validation and encoding, handle different send text types and capabilities, implement proper error handling for send text failures, optimize send text operations for performance, and maintain send text integrity throughout the process.
