You can try SeaBass by compiling the sample program to the left or by entering your own program (see the Seabass Manual for more details).

Notes:

• You can't use INCLUDE
• The demo is limited to 10 lines of input
• The -l option is in effect so no #line directives are generated
• The -c option is in effect so no C compilation occurs
• After you select an example or change the code, press Compile

There are a few differences between SeaBass and Basic:

• All variables must be declared with Dim or Array
• Comments at the end of a line start with ` (a back quote) instead of an ordinary quote
• Arrays use square brackets ([]) for indices
• Identifier names for variables, functions, and subroutines are case sensitive
• Calling a subroutine or a function with no arguments still requires empty parenthesis
• Functions return a value via the RETURN statement
• You must avoid using words reserved by your C compiler as identifiers even if they are legal Basic identifiers
• Parameters are passed to functions and subroutines by value, not by reference (that is, functions and subroutines receive copies of their arguments by default)
• There is no GOSUB statement (SeaBass uses named functions with formal parameters)
• SeaBass does not support Basic string handling (although you can use C-language strings with no problem)
• SeaBass uses C-language operators, most of which are the same as their Basic equivalents; a few are different (for example Basics MOD operator is % in SeaBass, hex numbers use 0x as in 0xFF)
• There is one exception to the last rule. Although C uses == and != as operators, SeaBas recognizes = and <> for these operations just as Basic does
