``` BANK NEW a BANK a LINE 2,2 ERASE 2,2 LIST ``` and finally: ``` BANK a MERGE ``` You'll see that the line you erased with **ERASE 2,2**, is back into place *NextZXOS* also provides one more command we've already seen but haven't sufficiently explained yet: [**BANK** *n*] **LIST** [#*c*] [**PROC** *name*()] which just lists the program (and optionally redirects its output to a stream) that's currently in memory. Optionally **LIST** can produce the list of the program that's currently in **BANK** *n*, or list a program whether banked or not starting with the procedure **name()** #### %CODE *NextBASIC* options are controlled by the special **%CODE** integer variable. This is reset to zero when a program is loaded/run. Currently available options are: | Bit | Use | | --- | --- | | **0** | if set, **%RND** n and **RND(n)** return values between **0..n**, rather than **0..–1** | | **1** | if set, the **BREAK** key is disabled | ### The Browser In order to allow easier navigation of your files, *NextZXOS* comes with the *Browser*, a program that allows you to do so in a visual way. The *Browser* features the following: - Easy navigation of drives and folders - File management facilities: copying, erasing, renaming and moving of files - Quick virtual disk mapping - Automatic launching of known file types - Extensible architecture for launching - Cursor key or joystick navigation The *Browser* is launched by using the **EDIT** key to bring up the *NextZXOS menus* or directly upon bootup by selecting the first entry in the *NextZXOS Startup menu*. #### The Browser Window Once the menu is selected and **ENTER** is pressed, the screen changes to the *Browser* window containing a list of the files located in the *default drive and folder* (as set by the **CD**, **LOAD**, **SAVE**, **MERGE** or **VERIFY** commands in *NextBASIC*). Normally upon initial boot this will be **c:/** but subsequent runs without a complete power down may show different locations reflecting the last drive and folder set as default. Note that you do not need to switch to *NextBASIC* to set a default drive and folder. Whatever you select with the *Browser* has the exact same effect for *NextBASIC*, as giving one of the aforementioned commands.
