Used by the routines at ProcessObjectDisplay and CheckAndResetCharacterState.
Clears the object-processing flag, reads this object's attributes, and prints the tokens the display bits select.

| 41893 | BIT 3,C | |||
| 41895 | JR Z,ProcessObject_Display_0 | |||
| 41897 | BIT 5,C | If bit 5 of the token is set, call ExtractTokenFromText to extract the token. | ||
| 41899 | CALL NZ,ExtractTokenFromText | |||
| 41902 | LD A,(40990) | If bit 7 of the saved token is set, call ExtractTokenFromText to extract the token. | ||

| 41907 | CALL NZ,ExtractTokenFromText | |||
| 41910 | LD A,(41822) | Jump to ProcessObject_Display_Next if the saved object field at 41822 is not 254. | ||
| 41913 | CP 254 | |||
| 41915 | JR NZ,ProcessObject_Display_Next | |||
| 41917 | PUSH HL | Point HL at DisplayPointer and call ShiftTextPointer, keeping the saved pointer. | ||
| 41918 | LD HL,(41007) | |||
| 41921 | CALL ShiftTextPointer | |||
| 41924 | POP HL | |||
| 41925 | JR ProcessObject_Display_0 | The picture marker has been handled and the saved pointer is already back in HL, so carry on at ProcessObject_Display_0. | ||
|
Compare this object with the character being processed, and take the token at 1371 when they match.
|
||||
| ProcessObject_Display_Next | 41927 | PUSH HL | Jump ahead to ProcessObject_Display_DisplayModePicture if this object is not the character being processed. | |

| 41932 | JR NZ,ProcessObject_Display_DisplayModePicture | |||
| 41934 | LD DE,1371 | Take 1371 for the object, then call PrintTextToken to print token 1371. | ||
| 41937 | CALL PrintTextToken | |||
| 41940 | JR ProcessObject_Display_WorkspaceBringingSaved | The token for the character being processed has been printed, so skip the location data and carry on at ProcessObject_Display_WorkspaceBringingSaved. | ||
|
When the display mode is the picture marker, run the location data in the saved object fields.
|
||||
| ProcessObject_Display_DisplayModePicture | 41942 | LD A,(40975) | Read the display mode. | |
| 41945 | CP 5 | See whether the display mode is 5 and read the saved object field at 41822, then call ProcessLocationDataIfValid to run location data if valid. | ||

| 41950 | CALL ProcessLocationDataIfValid | |||
| ProcessObject_Display_WorkspaceBringingSaved | 41953 | POP HL | Restore the saved pointer from the stack. | |
| ProcessObject_Display_0 | 41954 | LD A,(41823) | Jump ahead to PrintFullStop if the saved object field at 41823 is 255. | |
| 41957 | CP 255 | |||
| 41959 | JR Z,PrintFullStop | |||
| 41961 | BIT 2,C | Jump ahead to PrintFullStop if bit 2 is clear. | ||
| 41963 | JR Z,PrintFullStop | |||
| 41965 | BIT 5,C | If bit 5 of the token is clear, call ExtractTokenFromText to extract the token. | ||
| 41967 | CALL Z,ExtractTokenFromText | |||
| 41970 | LD A,(40990) | If bit 7 of the display flag at 40990 is clear, call ExtractTokenFromText to extract the token. | ||
| 41973 | BIT 7,A | |||
| 41975 | CALL Z,ExtractTokenFromText | |||
| 41978 | LD A,(41823) | Jump to ProcessObject_Display_OtherDisplayMode if the saved object field at 41823 is not 254. | ||
| 41981 | CP 254 | |||
| 41983 | JR NZ,ProcessObject_Display_OtherDisplayMode | |||
| 41985 | LD HL,(41009) | Read the display pointer, then call ShiftTextPointer to handle the picture for this message. | ||
| 41988 | CALL ShiftTextPointer | |||
| 41991 | JR PrintFullStop | Jump ahead to PrintFullStop to take 46 and jump to Print_Character. | ||
|
When the other display mode is the picture marker, run the location data in the saved object fields.
|
||||
| ProcessObject_Display_OtherDisplayMode | 41993 | LD A,(40976) | Read the display mode. | |
| 41996 | CP 5 | See whether the display mode is 5 and read the saved object field at 41823, then call ProcessLocationDataIfValid to run location data if valid. | ||
