OMG! ! I'm going crazy!

Read this passage carefully and try to understand it: Grammar: [Function module identification = N_M_X_Y_Z] N is the column ID: 1. When it is 0, it means all the contents of this function module; 2. Specific column ID; 3. For a certain range of column IDs, enter A-B, for example, a=1002 column, below column a, b=1003, c=1004, d=1005. To display all column titles below a, use 1003-1005; Another method is to specify multiple column IDs, input with | to distinguish: 1003|1004|1005 4. The upper-level column ID is not supported, so the third method is used. M is the number of returned items, up to 20 items. (When Y=-1 of the picture and album module displays the picture without line wrapping, -2 displays the picture without line wrapping) Z is the layout effect, ranging from 0 to 100. For example, when downloading the module, 0 displays only the title, 1 displays the column + title, 2 titles + date, 3 time + title, 4. Serial number + title, 5 desktop download effects, please note that some modules do not have this function and can only be set to 0. ||. No matter if you are crazy or not. Anyway, I'm going crazy. . .
