+There is a way to do this using loadfunction:
+<code lua>
 -- mprog 31404
 function a_function( arg1, arg2 )
+    say("Arg 1: "..arg1)
-  say("Arg 1: "..arg1)
+    say("Arg 2: "..arg2)

-  say("Arg 2: "..arg2)

 end
 -- mprog 31405
 target_mob = getmobworld(31424)[1]
 target_mob:loadprog(31404)
 target_mob:loadfunction( function()
+    a_function( "test1", "test2" )
-  a_function( "test1", "test2" )
 end)
 -- alternate mprog 31405
 target_mob = getmobworld(31424)[1]
 target_mob:loadfunction( function ()
+    loadprog(31404)
-  loadprog(31404)
+    -- alternately: target_mob:loadprog(31404)
+    -- alternately : mob:loadprog(31404)  -- 'mob' in this case would be target_mob because this function runs in target_mob's env
-  -- alternately: target_mob:loadprog(31404)
+    a_function( "test1", "test2" )
-  -- alternately : mob:loadprog(31404)  -- 'mob' in this case would be
-target_mob because this function runs in target_mob's env
-  a_function( "test1", "test2" )
 end)
 -- mprog 31405 with return value
 -- note, 'mob' is not a function variable, but a global variable to the
 environment
 -- uses closure magic to move values between script envs
 local result
 target_mob = getmobworld(31424)[1]
 target_mob:loadfunction( function ()
+    loadprog(31404)
-  loadprog(31404)

 Not as pretty as something like target_mob:loadprog( 31404, "test1", "test2" ),
 but there is no straightforward way to implement args to loadprog directly.
 For instance, if I used the syntax above, by what name would you
 refer to those parameters in the 31404 script?
 So loadfunction is the way to do tricky stuff like this, for better or worse.
 I agree, it's often nice to have all the code in one place.
 loadfunction can't directly return a value, but you can use other tricks to
 get the job done:
-[code lua]
+<code lua>
 -- mprog 31405 with return value
 -- uses closure magic to move values between script envs
 local result
 target_mob = getmobworld(31424)[1]
 target_mob:loadfunction( function ()
+    loadprog(31404)
-  loadprog(31404)
+    result=a_function( "test1", "test2" )
-  result=a_function( "test1", "test2" )
 end)
