CMNDPROC.BAS is the main module that contains the core business logic and processing functionality, while Cmdproc-1.frm through Cmdproc-6.frm are the form modules that provide the user interface components:
|
||
|
|
|
||
|
|
1. CMNDPROC.BAS:
|
||
|
|
- Contains all the core functions for file operations, command processing, and system management
|
||
|
|
- Handles the actual processing of commands and file operations
|
||
|
|
- Manages communication between components
|
||
|
|
- Contains global variables and configuration settings
|
||
|
|
|
||
|
|
2. Form Relationships:
|
||
|
|
- Cmdproc-1.frm: Main interface form that displays status, logs, and controls
|
||
|
|
- Cmdproc-2.frm: Handles printer and plotter configuration interface
|
||
|
|
- Cmdproc-3.frm: Manages file viewing and selection interface
|
||
|
|
- Cmdproc-4.frm: Provides command entry and monitoring interface
|
||
|
|
- Cmdproc-5.frm: Shows system status and diagnostic information
|
||
|
|
- Cmdproc-6.frm: Contains settings and configuration interface
|
||
|
|
|
||
|
|
The forms access the functions and variables in CMNDPROC.BAS to:
|
||
|
|
- Display status information
|
||
|
|
- Trigger command processing
|
||
|
|
- Show operation results
|
||
|
|
- Configure system settings
|
||
|
|
- Monitor system state
|
||
|
|
|
||
|
|
CMNDPROC.BAS acts as the central processing module while the forms provide the UI layer for user interaction with the system.
