Using CA IDMS Schema Mapper's Parameters

The PROCESS statement is the only mandatory parameter statement. The other statements (OPTIONS, CHARDEF, DRECLINE, XRECLINE, DSETLINE, XSETLINE, INCLUDE AREA, and LOCATE) are optional. The optional statements are used when you want to modify the layout or the format of the data structure diagram produced by using a single PROCESS statement.

Creating data structure diagrams with CA IDMS Schema Mapper can be either a one-step or a two-step procedure. It is quite likely that you will be satisfied with the diagram created automatically, and you will follow only the first step.

Step 1--Use one PROCESS statement (mandatory) to create a diagram with automatic layout and default format.

Step 2--Assess the diagram and then make desired changes by using one or more of the optional parameter statements.

When you execute CA IDMS Schema Mapper, one of its outputs is a Transfer File that contains parameter statements. You can use this file as input to recreate a diagram. You can also modify the parameter statements in the Transfer File to tailor or revise a diagram. Exhibit 2.3 lists all of CA IDMS Schema Mapper's parameters.
