Form Integration

CMNDPROC.BAS serves as the core command processing module that integrates with the following forms:

Cmdproc-1.frm

• Main command processing interface
• Handles primary user input and command validation
• Interfaces with system management functions
• Manages initial command queue processing

Cmdproc-2.frm

• File operation handling
• Implements file type validation
• Manages file conversion processes
• Controls file queue management

Cmdproc-3.frm

• Network communication interface
• Processes network print requests
• Handles network path resolution
• Manages network queue status

Cmdproc-4.frm

• Security and access control
• User authentication interface
• Printer group management
• Access logging implementation

Cmdproc-5.frm

• Error handling interface
• Displays error messages
• Manages error recovery procedures
• Logs error information

Cmdproc-6.frm

• System monitoring interface
• Performance tracking
• Resource usage display
• System status reporting

Integration Flow

CMNDPROC.BAS ⟷ Cmdproc-1.frm ⟷ [Cmdproc-2.frm through Cmdproc-6.frm]

• Core functions in CMNDPROC.BAS are called by form modules
• Forms provide UI elements for command processing functions
• Each form specializes in specific system aspects
• All forms communicate through CMNDPROC.BAS central control
