This syntax will erase the screen(terminal/console) before sending map specified.
So it will send a new map without any overlapping fields.
Try out removing the ERASE option. You will see the difference. |

Where does it mention in your post ---You need a difference.
The basic difference is that low-values will just initialize your symbolic map variables. So when you send the map to the terminal, all the UNPROT fields will appear empty but still the physical map(PROT fields) will be appear.
For ERASE option read my previous post. |

Not to worry - if this was the very worst thing to happen this year, it would be a very good year 
One of the biggest challenges we have in the forum is the English language. . .

There is a link to manuals at the top of the page. If you click on it, find the CICS Programming Guide, you can find

6.3.2 Initializing the output map
Before you start building your output, make sure that the map storage is initialized to nulls, so that data left there by a previous process is not used inadvertently. If you have read input data using this same map, or one that overlays it, you need to ensure that you have processed or saved this data first. The relationship between input and output maps is discussed in "The symbolic input map" in topic 6.5.1.1, and using the same map you used for input is discussed in "Sending mapped output after mapped input" in topic 6.5.10.
You initialize by moving nulls (X'00') into the structure. The symbolic map structures are defined so that you can refer to the whole map area by the name of the map suffixed by the letter O. You can see this in Figure 142 in topic 6.1.2, and, in fact, the statement:
MOVE LOW-VALUES TO QCKMAPO.
would clear the area in which we built the map in the "quick check" example. If you are using the map for both input and output, it may be easier to clear the map one field at a time, as you edit the input (see "Handling input errors" in topic 6.5.9).
When you obtain map storage with a CICS GETMAIN instruction, another way to initialize is to use the INITIMG option. |
