|
The `stdio` module automatically imports the `string` and `err` modules.
|
|
|
|
|
It requires an implementation of `void putchar(byte a)` and therefore works only on targets with console output.

|
|
|
On targets with idiosyncratic behaviour of `putchar`, functions in this module inherit that behaviour.

#### `void putstr(pointer str, byte len)`
|
|
|
|
|
|
|
|
|
|
Prints a string of length `len` located at address `str`.
|
|
|
|
|
|
|
|
|
|
#### `void putstrz(pointer str)`
|
|
|
|
|
|
|
|
|
|
Prints a null-terminated string located at address `str`.
|
|
|
|
|
If the string is longer than 255 bytes, then the behaviour is undefined (might even crash).
|
|
|
|
|
|
|
|
|
|
#### `void putword(word w)`
|
|
|
|
|
|
|
|
|
|
Prints the decimal representation of the 16-bit unsigned integer `w`.
|
|
|
|
|
|
|
|
|
|
#### `void ensure_mixedcase()`
|
|
|
|
|
|
|
|
|
|
On targets that have separate all-caps and mixed-case modes (like most Commodore machines), switches to the mixed-case mode.
