Most Efficient Symbol/Letter for Separating Text

Okay smart guy, tell me what this does:

AniBOB_PositionX(ThisEnemy\BOB, -32, 200-32,  500, 3, 1, 0, False, 0)
AniBOB_PositionY(ThisEnemy\BOB, 500,    100, 1000, 0, 0, 0,  True, 0)

No idea? That's not surprising. Heck, I wrote that function and I couldn't even tell you what that line does exactly. Not without searching for the function and reading the names of the parameters.

But if I comment that line like so:

; AniBOB_Frame(BOB.BOB, Start_Frame, End_Frame, Anim_Time, Anim_Mode, Anim_Velocity, New_Image=0, Trigger_Delay=0, Free_BOB=False, StartAge=0)

   AniBOB_PositionX(ThisEnemy\BOB, -32, 200-32,  500, 3, 1, 0, False, 0)
   AniBOB_PositionY(ThisEnemy\BOB, 500,    100, 1000, 0, 0, 0,  True, 0)

Well now I have a lot more information. I'll still have to look up Anim_Time and Anim_Mode to see what they are six months from now, but right now at least I remember what the different values mean.

A better comment however would be the following, becayse while the above does show me what the function parameters mean, it doesn't tell me what that code DOES.

; AniBOB_Frame(BOB.BOB, Start_Frame, End_Frame, Anim_Time, Anim_Mode, Anim_Velocity, New_Image=0, Trigger_Delay=0, Free_BOB=False, StartAge=0)

; Make enemy follow a half circle path emerging from the left side of the screen.
   AniBOB_PositionX(ThisEnemy\BOB, -32, 200-32,  500, 3, 1, 0, False, 0)
   AniBOB_PositionY(ThisEnemy\BOB, 500,    100, 1000, 0, 0, 0,  True, 0)
