Okay, I'm going to ask because the other people in the discussion haven't done so yet. Not that they aren't reluctant to ask, but the one wanting the code has been away from the forums for awhile and hasn't gotten caught up here. So, Miloch, if you see this I've asked for you...
Thread/posts at Spellhold concerning the topic:
http://www.shsforums.net/index.php?showtopic=40544&st=0#Basically it boils down to a desire to do
STRING_SET @1 @2 where the first tra number equates to the string text of a previously added mod and the second number is the tra entry for the replacement text string.
To give a working example as I understand it: Mod A installs dialog and stuff. Mod B also installs dialog and stuff but needs to adjust one or two words in one maybe two strings of Mod A's dialog. Given the nature of multiple install orders the string reference number for the dialog.tlk is unknown. In this example, multiple languages need to be dealt with. Using a TRA value in both entries will be much easier and simpler because then both entries can be keep together in each language folder.
Thanks in advance for your thoughts.
