Summary

Important Observations

• There are many ways of coding RDML statements to achieve the same results. For example, the following two statements will produce the same result:

CHANGE FIELD(#STD_TEXT) TO(*BLANKS)

 

#STD_TEXT := *BLANKS

 

     The second statement is an example of the ASSIGN command and is the recommended code.

• The DEFINE_COM statements may be hidden using the editor settings.

Tips and Techniques

• Review all of the editor settings to determine the options that you want to use when working in Visual LANSA.

• When editing source code, using the Auto Hide tab feature will enable the maximum amount of space for viewing your source code.

• F2 provides Features about components. The F1 online help will provide details about the user interface, commands, and options.

• Use the dialog box launcher in the Compile group in the ribbon if you need to specify the compile settings. If you submit compiles using the Compile command, the compile options will simply default to the last values set in the Compile options dialog.
