OSWORD &00

OSWORD &00 ( 0 ) - Input line Acorn MOS 1.20

On entry:
 XY?0..1=>string buffer
 XY?2   =maximum line length
 XY?3   =minimum acceptable ASCII value
 XY?4   =maximum acceptable ASCII value
On exit:
 Y is the line length (excluding CR)
 Cy=1 if Escape terminated input

Note that this is the only OSWORD call that legally returns values
in the registers.

Note that the maximum line length at XY?2 does not count the CR, so
XY?0..1 must point to at least 1+XY?2 bytes of free memory.
