Yay, your online again!
Anyways, there is no callasm involved. Set the variable 4052 (Or the one you chose), and do a normal textbox while in fadescreen. Then set 4052 back to 0. To change the textbox to the middle, use
writebytetooffset 0x6 0x020204b4. 0x6 is the 8x8 block position from the top. The default is 0xF.
As for the previously on your journey thing, it's at
