So I guess when I savevar from an include, the include's filename is prepended... I didn't realize that - seems a bit strange to me, because an included file could also be a stand-alone. I guess it makes sense.

XIde's documentation doesn't seem to cover stuff like referencing included vars and subs. Is there more documentation somewhere? I think the only place I know of that even mentions the ~ operator is this forum.

I thought I was starting to understand twx scripting, but I think I'm still missing some important info. Can anyone tell me what's wrong with this (i.e. why the output says '0' instead of 'testing123'? scripts/test_main.ts: -------------------------------------------------------------------------- include "test_vars.ts" loadVar $testVar echo "Loaded testVar from main is " &$testVar& "" halt -------------------------------------------------------------------------- scripts/test_vars.ts: -------------------------------------------------------------------------- setVar $testVar "testing123" saveVar $testVar echo "* saved testVar as " &$testVar& "*" -------------------------------------------------------------------------- output: -------------------------------------------------------------------------- Loading and compiling script: scripts\test_main.ts Citadel command (?=help) saved testVar as testing123 Loaded testVar from main is 0 Script terminated: scripts\test_main.ts -------------------------------------------------------------------------- I thought saveVar always associated with the current twx db, so it doesn't matter where I access it as long as it's the same db? It works if I call it $test_vars~testVar from main, but the var is saved, so why do I have to reference it like that? Does saveVar prepend the filename to the varname??

If i stick a pause before the halt in test_main, and then dump vars with "test" in the name, i get the following. -------------------------------------------------- "$TESTVAR" = "0" "saved testVar as testing123 "$TEST_VARS~$3" = "testing123 "$TEST_VARS~TESTVAR" = "testing123" -------------------------------------------------- A couple questions... - Where the heck does $TEST_VARS~$3 come from, and why are there two dollar signs in the name? I read somewhere that there should be only one dollar sign, in the first part of the composite name? - Where are the closing quotations in the second and third lines of the dump? - Why is $TESTVAR = 0 if I called saveVar $testVar?

Replace your test_main.ts with the following: # test_main.ts # include "test_vars.ts" # prepending the saveVar variable from the include with the include name loadVar $test_Vars~testVar echo "Loaded testVar from main is " $test_Vars~testVar "" halt -------------------------------- If you look in \twx\data you will find a .cfg file with the same name as your gamename that you used in TWX's setup. You can view the SaveVars there.

Thank you Promethius... that data file is valuable information. So I guess when I savevar from an include, the include's filename is prepended... I didn't realize that - seems a bit strange to me, because an included file could also be a stand-alone. I guess it makes sense. Any insight on the extra $ or the missing " in the var dump? Are those just minor bugs in twx?

Are those just minor bugs in twx? Not sure on the extra $ as I did not see that in my var dump. The missing " may be the result of setting a var = "something" -- the would probably cause the ending quote to dissapear. You might want to test that.

Is there more documentation somewhere? I think the only place I know of that even mentions the ~ operator is this forum. Documentation is pretty slim in regard to TWX. EP is setting up a site that will help, and Thrawn has information on his site (outpost-4.com/tradewars). NazHaz.com has some information - check the twcabal link and Sing's macro examples. The macros are not exactly TWX, but knowing how to put a string together for TWX to output is extremely important IMHO. Bad things can happen when your send command spews out game commands w/o handling different situations.
