Shodan BASIC is a .NET Core application to interpreter the BASIC (Beginners' All-purpose Symbolic Instruction Code) programming language.
This language is easy to learn and flexible enough to offer a great entry in to programming. Shodan is still in active development and required Microsoft .NET Core 3.1 or greater to run. Newer version from 0.1.0.0 require .NET 5.0 or greater.
Version 0.0.1.0 - Migrated to .NET 5.0
Version 0.0.0.1 - Initial limited alpha build.
LET - assigns a value (which may be the result of an expression to a variable.
FOR repeat a section of code a given number of times. A variable that acts as a counter is available within the loop.
PRINT- displays a message on the screen or other output device. Print accept the use of variables when used outside of quotation marks.
PRINT Another Test
LET myVal = "Example"
INPUT - asks the user to enter the value of a variable. The statement may include a prompt message.
The following commands are not specific to the BASIC language but are used to operate features of the interpreter. All commands and keywords can be entered in to the application with and without prefixing a number. In the event a number is not prefixed, representing the line number, the system will append the new line to the end of the code. If a line number is prefixed and that line exists, the current line will be replaced. If a line is entered with a prefix number, but without a keyword, the line is removed from code. The above can also be used in insert code by prefixing a number not currently in use, between the numbers already in RAM.
LOAD - Loads a saved code file in to RAM and clears current buffer.
SAVE - Saves the current buffer to file.
LIST - Displays the lines of code currently in the buffer
LIST 10 Only the line 10 of this program is listing on screen.
LIST -10 All lines until line 10 of this program are listing on screen.
LIST 10- All lines beginning with line 10 of this program are listing on screen
NEW - Clear the buffer and the display and restarts the session.
CLEAR - Clears display, but keeps code in RAM.
SHOW - Displays information about different systems.
RUN - Execute the code in RAM.
EXIT - Exits the application.
