Screen-to-HTML Modern View

Modern View renders the current green screen as a clean HTML form alongside the terminal. You can fill fields in the form instead of typing on the terminal, IMTerm keeps both in sync. This tutorial shows you how to enable it, use it, and customise it with templates.

Connect to your AS/400 and reach a data-entry screen

Modern View works best on screens with input fields, like Customer Maintenance, Sign On, or any AS/400 form. Connect to your session and navigate to such a screen.

What you should see: A typical green-screen form with labelled input fields (e.g. Customer Number, Company Name, Address).

Open Modern View

Click View > Modern View in the menu bar. Modern View opens as a panel on the right side of the terminal, no page reload required.

What you should see: The terminal shrinks to make room and a styled HTML form appears on the right. Each field label from the green screen is shown as a form label, and each input field becomes an HTML text box.

See the split view

Both views are active simultaneously. The terminal on the left shows the live host screen; the HTML form on the right reflects the current field values.

What you should see: A split layout. The green-screen terminal is on the left at reduced width. The right panel shows field labels (Customer Number, Company Name, etc.) with text inputs containing the current values from the screen.

Edit a field in the HTML form

Click on any text input in the right panel and type a value. You do not need to click on the terminal, the HTML form accepts input directly.

What you should see: The text cursor appears in the HTML input. You can type, backspace, and paste text normally. The green screen is not updated yet, changes are buffered until you press an action key.

Send the form to the host

Press the Enter button at the bottom of the HTML form (or press Enter in any field). IMTerm packages all the field values and sends them to the host exactly as if you had filled the green-screen fields manually.

What you should see: Both the terminal and the HTML form update to show the host's response. If the record was saved successfully you see a confirmation message; if validation failed, the host returns an error message and keeps the same screen.

Use F-key buttons

The bottom of the HTML panel also shows F-key buttons (F3=Exit, F5=Refresh, etc.) extracted from the green screen. Click them to send the corresponding F-key to the host without touching the terminal.

What you should see: A row of labelled buttons corresponding to the F-keys shown in the green screen's bottom rows (e.g. "F3 Exit", "F5 Refresh"). Clicking one closes the screen or refreshes the form just like pressing the physical key.

Print the Modern View form

Click the Print button in the Modern View toolbar. This triggers a browser print that automatically hides the terminal and prints only the HTML form, clean, no green-screen borders.

What you should see: The browser print dialog opens. The preview shows only the styled HTML form on a white background, ready to print or save as PDF.

Try a custom template

Click the Templates button in the Modern View toolbar to open the Template Editor. You can see built-in templates (like CUSTMNT for Customer Maintenance) and create your own for other screens. Templates use the screen title to auto-apply.

What you should see: The Template Editor opens. Built-in templates show a two-column card layout with grouped fields. Navigate to the CUSTMNT screen and the polished Customer Maintenance template appears automatically.
