# E4104

Current loop expects different number of arguments than supplied with `continue`.

This error occurs when the number of arguments provided to a `continue`
statement does not match the number of arguments expected by the loop. In a
`for` loop with explicit loop variables, when using `continue` with arguments,
you must provide the same number of arguments as declared in the loop header.

For example, if a `for` loop has two loop variables, any `continue` statement
with arguments within that loop must also provide exactly two arguments.
Providing too few or too many arguments will trigger this error.

Note that in a `for` loop, you can omit all arguments in a `continue` statement.
In this case, the loop will use the update expressions specified in the loop
header. However, if you do provide arguments to `continue`, the number of
arguments must match the number of loop variables.

For example, in a `for` loop with two variables:

- `continue` (with no arguments) will use the default updates
- `continue x, y` (with two arguments) is valid
- `continue x` or `continue x, y, z` will trigger this error

## Erroneous example

```{literalinclude} /sources/error_codes/4104_error/top.mbt
:language: moonbit
```

## Suggestion

To fix this error, ensure that the number of arguments provided to `continue`
matches the number of loop variables. For example,

```{literalinclude} /sources/error_codes/4104_fixed/top.mbt
:language: moonbit
```
