LINPRT ... that's helluva lot of code just to print an unsigned 16-bit int. The only good news is that it is built-into ROM.

Usage:

LDA #$12
LDX #$34
JMP $ED24

Output:
4660

NOTE: Stack $100 .. $1104 is used as output buffer.

Requires:

* $E000 Basic Cold Start or
* $E003 Basic Warm Start

must be called first.

To document for posterity:

I wanted to use LINPRNT without fully initializing Basic. Assuming at least ProDOS has started (i.e. you're in a SYS file), it appears you can get away with just the following:

SHIFT.SIGN.EXT set to 0; required by FP routines
TEMPPT set to TEMPST; it's a string descriptor pointer
SPEEDZ set to 1, for no output delay
FLASH.BIT set to 0, to get normal characters

Equates per http://www.txbobsc.com/scsc/scdocumentor/definitions.html
