Keyword Table

Root / Documentation / [.]

Created:
A *keyword* is a special identifier reserved by the language syntax. They are used for control structures and special language features. A keyword cannot be used as a name for a variable or user-defined function in most cases. > *Note:* do not confuse keywords with operators. The "word" operators `DIV` `MOD` `AND` `OR` `XOR` and `NOT` are also treated as keywords, but are listed in the sbs:page/3164[Operator Table]. * Declarations/Variables |* Keyword | Description | | `VAR` |#rs=2 Declares a variable or array. | | `DIM` | | `VAR()` | Refer to a variable given its name as a string. | | `DIM()` | Check the dimensions of an array. | | `DEF` | Starts a function definition. | | `COMMON` | Comes before `DEF` to mark this function as available to all slots. | | `INC` | Increment a variable or append to a string. | | `DEC` | Decrement a variable. | | `SWAP` | Swaps the values of two variables. | | `DEFOUT` | Set a return value by position. Only usable within user-defined functions. | | `OUT` | Specifies the return value list of a function. | | `CONST` | Declare a constant. | | `ENUM` | Declare an enum. | * Control Structures ** General |* Keyword | Description | | `END` | Ends the program, or marks the end of a function definition. | | `RETURN` | Returns from a `GOSUB` or `DEF`.\ Within expression-style `DEF`, `RETURN` accepts a return value. | | `EXEC` | Executes a program or slot. | | `CALL` | Call a function given its name and parameters. | | `BREAK` | Exit the loop immediately.\ When used with `ON BREAK GOTO`, specify the label to `GOTO` when Plus is pressed. | | `CONTINUE` | Skip to the next iteration of the loop. | ** IF Statements |* Keyword | Description | | `IF` | Starts an `IF` statement. | | `THEN` | Comes after the condition in an `IF` or `ELSEIF` (except when using `GOTO`.) | | `ELSEIF` | Starts an `ELSEIF` branch in a multi-line `IF`. | | `ELSE` | Starts the `ELSE` section of an `IF` statement. | | `ENDIF` | Ends a multi-line `IF` statement. | ** CASE Statements |* Keyword | Description | | `CASE` | Starts a `CASE` statement, specifying the case value. | | `WHEN` | Specifies a possible match for the `CASE` statement. | | `OTHERWISE` | Specifies the path to take when nothing matches (or, matches anything.) | | `ENDCASE` | Ends the `CASE` statement. | ** LOOP |* Keyword | Description | | `LOOP` | Starts a `LOOP`. | | `ENDLOOP` | Ends a `LOOP`. | ** FOR Loop |* Keyword | Description | | `FOR` | Starts a `FOR` loop. | | `TO` | Specifies the end value.\ `TO` is only a keyword when used in the context of a `FOR` loop. | | `STEP` | Specifies the step value.\ `STEP` is only a keyword when used in the context of a `FOR` loop. | | `NEXT` | Ends a `FOR` loop. | ** WHILE Loop |* Keyword | Description | | `WHILE` | Starts a `WHILE` loop, specifying the loop condition. | | `WEND` | Ends a `WHILE` loop. | ** REPEAT Loop |* Keyword | Description | | `REPEAT` | Starts a `REPEAT` loop. | | `UNTIL` | Ends a `REPEAT` loop, specifying the loop condition. | ** GOTO |* Keyword | Description | | `GOTO` | Jump to the given label. | | `GOSUB` | Jump to the given label, as a subroutine.\ The label can be returned from using `RETURN`. | | `ON` | Starts an `ON` statement. | * Text Screen / Console |* Keyword | Description | | `PRINT` |#rs=2 Print values on the console text screen. | | `?` | | `TPRINT` |#rs=2 Print values on a text screen. | | `T?` | | `INPUT` | Read values from keyboard input on the console screen. | | `LINPUT` | Read a line of keyboard input on the console screen. | | `??` | Special alias of the `INSPECT` function. | * DATA |* Keyword | Description | | `DATA` | Starts a `DATA` statement. | | `READ` | Read values from the current `DATA` position. | | `RESTORE` | Set/push/pop the `DATA` read position. | * Other |* Keyword | Description | | `REM` | Starts a comment. |
Small issue: The "operator table" link incorrectly points to this page instead of the operator table.

I think something went sideways with links as part of the import (all of these pages are exported from SBS2) so I'll have to fix pretty much all of them.

ohhhh um... well that's kind of unfortunate. I don't know how all the hops between new/old/sbs work, it's probably an oversight, I'm sorry.

The links were just page IDs so I don't think they could be reasonably fixed until after import, anyway.
