Definitions on the following list are frequently provided by the default automatically-imported modules.
However, as they are not the part of the standard library, they might not be available on all targets:
void init_rw_memory()
Initializes all writable arrays and variables with their initial values.
If the preprocessor feature INIT_RW_MEMORY is defined and non-zero,
then init_rw_memory is available and should be called before accessing any preinitialized writable object.
If the preprocessor feature INIT_RW_MEMORY is not defined or is zero,
then init_rw_memory is not available.
void putchar(byte char)
Prints a single character.
Available for: all computer targets.
Uses ROM routines, so requires the appropriate ROM to be enabled if applicable.
Note that this function may obey typical platform idiosyncrasies, for example:
-
on Commodore PET targets the quote character toggles the quotation mode
-
printing past the end of line might insert a blank line below the current one
-
printing past the end of the screen might ask the user to confirm scrolling
The exact behaviour is platform-dependent. Future library versions will strive to eliminate those issues.
void new_line()
Moves the cursor to the next line.
Available for: all computer targets.
Uses ROM routines, so requires the appropriate ROM to be enabled if applicable.
pointer readline()
Reads a line from the console and returns a pointer to a null-terminated string. The string is valid only until next read from the console.
Available for:
ZX Spectrum,
NEC PC-88,
MSX,
Apple II,
Robotron Z1013 (always trims trailing spaces),
TRS-80,
VIC-20 (except for vic20_a000),
Commodore 64 with c64_basic module (requires KERNAL and BASIC; empty input is treated like a single space),
Commodore 16 or Plus/4 with c264_basic module (requires KERNAL and BASIC; empty input is treated like a single space).
word readword()
Reads a 16-bit unsigned integer from the console.
Available for:
ZX Spectrum,
NEC PC-88,
MSX,
Apple II,
Robotron Z1013,
TRS-80,
VIC-20 (except for vic20_a000),
Commodore 64 with c64_basic module (requires KERNAL and BASIC),
Commodore 16 or Plus/4 with c264_basic module (requires KERNAL and BASIC).
void bell()
Beeps.
Available for: Apple 2, ZX Spectrum. Uses ROM routines, so requires the appropriate ROM to be enabled if applicable.
void set_bg_color(byte color)
Sets the screen background color.
Available for: C64, VIC-20, C64, C128, C264 series.
void set_border(byte color)
Sets the screen border color.
Available for: VIC-20, C64, C128, C264 series, ZX Spectrum.
const byte black, white, red, green, blue, cyan, purple, yellow
Various colour constants.
Available for: VIC-20, C64, C128, C264 series, ZX Spectrum.
