BASIC Garbage Collection (GC) Patch
|
||||
---
|
||||
|
||||
The following information comes from BAS3FIX.TXT in the ["Fixed BASIC3 ROM"](http://osiweb.org/roms/basfix02.zip) ZIP
|
||||
archive at [osiweb.org](http://osiweb.org/software.html#BASIC_ROMS). The patch was created in 2001 and is attributed to
|
||||
"[Ed](http://dxforth.netbay.com.au/)" (formerly at http://www.netbay.com.au/~dxforth/).

New OSI/UK101 ROM BASIC garbage collection bug patch
|
||||
----------------------------------------------------
|
||||
|
||||
The 8K ROM BASIC supplied with the OSI Superboard II and
|
||||
UK101 computers contains a bug in the garbage collector
|
||||
routine (see Listing 1). A patch was subsequently made
|
||||
available in the form of an updated BASIC 3 ROM (for the
|
||||
UK101 at least). The code is shown in Listing 3.
|
||||
|
||||
Unfortunately the patch was not a complete solution and
|
||||
corrupted strings could still occur - see Listing 2.
|
||||
|
||||
Listing 4 shows a new garbage collector patch that fixes
|
||||
all the problems. It is a combination of the original
|
||||
patch with changes found in later versions of Microsoft
|
||||
6502 BASIC.
|
||||
|
||||
Implementing the patch requires replacing of the BASIC 3
|
||||
ROM. Binary and hex dumps for the new ROM are enclosed.
|
||||
|
||||
The patch and rom images suit either the OSI or UK101 ROM
|
||||
BASIC.
