Emergence BASIC's built in editor has many of the common features of a standard text editor with the addition of syntax coloring. With syntax coloring every statement or function that is a built in component of EBASIC is highlighted in a user selectable color. This makes your code more readable and easier to find errors.
Open a new program by selecting File and choosing New->Emergence Source File from the main menu bar and type in the following program statements in the new editor window.
OPENCONSOLE
PRINT "Hello World"
DO
UNTIL INKEY$ <> ""
CLOSECONSOLE
END
Notice the blue coloring of the EBASIC program statements. If you make a mistake and misspell a program statement you will immediately know due to its lack of color.
Now that we have some text in the editor we can explain some of the key commands the editor responds to.

There are other shortcuts available for use. Explore the main menu of the IDE to determine shortcuts to commonly used menu options.
Selecting Text
To select text for copying and cutting place the mouse cursor (I-Beam) over the first character of the text to select. Press the left mouse button down and ‘drag’ the cursor over the text to select. If you drag past the confines of the window it will automatically scroll allowing the continued selection of text until the beginning or the end of the document
If any key is pressed when text is selected then the selected portion will be replaced with the new text. The selected portion can also be deleted by pressing the <Delete> key.
Text may also be selected using the keyboard by holding the SHIFT key down and pressing one of <HOME>, <END>, <PAGEUP>, <PAGEDOWN>, or the arrow keys.
Text may also be selected from the current caret position to the position clicked with the left mouse button by holding down the SHIFT key.
Saving the file
To save the current program to file select File > Save from the main menu bar. The default extension for Emergence BASIC is .EBA and should not be changed to anything else. For include files the default extension is .INC
Editor options
You can modify many of the default characteristics of the text editor by opening the editor options dialog. Select the File menu and choose Editor Options... Syntax coloring, tab widths, line numbering and font used for text display is all user selectable. A mono-spaced, or fixed font is recommended for programming use. Some True Type fonts do not display line numbers well.
