Introduction to SCL Program Flow

You can control the flow of execution of your SCL application by

• using any of several programming constructs such as DO loops and IF/THEN-ELSE statements

• branching to labeled sections with the LINK statement

• branching to PROGRAM, FRAME, MENU, CBT, or HELP entries with the GOTO statement

• branching to another SCL entry with CALL DISPLAY

• executing a method that is stored in a separate SCL entry with CALL METHOD

• executing an object method by using dot notation

• sending a method to an object with CALL SEND

• sending a method to a FRAME entry control with CALL NOTIFY

• specifying how labeled sections are executed, when and where submit blocks are executed, and whether execution halts when errors are encountered in dot notation with the CONTROL statement

• creating a program halt handler to control how run-time errors are processed.

For more information about controlling the flow of execution in applications that use frames, refer to SAS Guide to Applications Development.
