Exits from a submenu and returns to the previous menu, or terminates a select, unloadtable or while loop, or a run submenu or display submenu statement.

The 4GL endloop statement can be used to break out of various sorts of loops. When used within a submenu created by an attached query or a run or display submenu statement, the endloop statement causes the application to exit from the submenu and return to the main menu of a frame. At the same time, endloop closes the attached query for the submenu.

Used within a select or while statement, endloop causes processing within the loop to terminate, transferring control to the first statement following endwhile or end. This is the only form of endloop that can optionally take a label as a parameter.

The label is useful within a nested series of while statements, to indicate which level of nesting to break out of. An endloop with a label causes control to break to the first statement following the endwhile for the labeled loop. See the while statement section for more information on labeled loops.

You can use the endloop statement to break out of an unloadtable loop without completing the processing of every row in the data set.

For additional information, see the sections in this chapter on the Select, unloadtable Statement—Loop Through Rows and Execute Statements, While, Run Submenu, and Display Submenu statements.

The End menu operation closes the submenu and its attached query:
