 Rather than delve into the intricacies of legacy scripting, it might be easier to write an over-ride OXP in javascript. See Sothis & [[SothisTC]] for an example. KillerWolf wrote Sothis in a mix of XML legacy script & javascript in 2010. Spara wrote a javascript override (improving the markets) which is currently (May 2021) being updated (reintroducing dockability ''etc'', which were all lost as Oolite changed).

-Older OXPs (from [[User:Aegidian|Aegidian]]'s day) were written in Legacy Script. So if you look, for example, at the innards of [[Benulobiweed Inc.|Charlie's Benulobiweed oxp's]] from 2006-7 they are all written in the legacy scripts. When Aegidian started writing Oolite it was purely for the AppleMac, hence the ability to overwrite portions of the vanilla game code in OpenStep (the Windows and Linux ports were written later by [[David Taylor]] & [[Dylan Smith]]). XML was also included as a valid OXP language.
+Older OXPs (from [[User:Aegidian|Aegidian]]'s day) were written ''entirely'' in Legacy Script. So if you look, for example, at the innards of [[Benulobiweed Inc.|Charlie's Benulobiweed oxp's]] from 2006-7 you will find that everything is written in the legacy scripts. When Aegidian started writing Oolite it was purely for the AppleMac, hence the ability to overwrite portions of the vanilla game code in OpenStep (the Windows and Linux ports were written later by [[David Taylor]] & [[Dylan Smith]]).

 '''Legacy script thus comes in two versions: XML & OpenStep.'''

 If you need more information, you can navigate to a relevant page and then inspect the original 2006 version (if there was one) by clicking on the ''history'' tab at the top of the page and comparing the early version with the current one. Ahruman started introducing Javascript after he took over from Aegidian which was in early/mid 2007. Since then, the relevant pages have been edited, replacing the legacy script with the newer Javascript. ''History'' restores the originals. Note that in a few cases (eg: Commodities.plist) the original legacy script no longer works.
