When you first use DDF you will only have a half dozen or so datasets on your display. But as you get used to it, you will soon find that you have more than one screen's worth and you will be continuously scrolling up and down searching for the ones you want, which becomes irritating and time consuming. The Show heading allows you to of organise the display to group logically related datasets together and either show or exclude them from the display as you choose.For example:
DDF 1.0 ------------- USERID1 Jun 1994 ------- ROW 1 FROM nnn Command ===> Scroll ===>PAGE Show list > < Cmd Member Text Description Show FRED PROJ1.QUAL2.QUAL3.QUAL4 ABC PROJ1.LEVEL2.QUAL3.QUAL4 ABC PROJ2.QUAL2.QUAL3.QUAL4 ABC BILL OTHERID.SOME.DATA.OR.OTHER ABD YET.ANOTHER.LEVEL P1 XYZ PROJ3.ANOTHER.DATSET RSTYou can type anything under the Show heading to identify related datasets, as in the display above where all the ABC project's datasets are grouped together. There are no special values that you have to enter under Show; numbers and special characters are just as good as letters. The Show column determines the order that the datasets are shown; lines with blank Show field of always being at the top of the display. You can control the display with these commands:
You can thus quickly reorder the complete display:
