COBOL

In order to work with COBOL masking routines, you need to have the COBOL environment configured:

For building the routines, you need the COBOL development environment.
For executing the routines, you need the COBOL run-time environment only.

Building COBOL Masking Routines

To create a COBOL masking routine:

Make a copy of the template masking routine UDCDEMO.CBL.
Update the PROGRAM-ID clause to include the name of your masking routine.

Insert your masking logic within the PROCEDURE DIVISION, after the following comment:

 * 
  * Insert processing logic here. 
	 *

Update the build script to add instructions for building the new module. For Windows platforms:

Step	Action	Details
1	Update the build.bat script.	Add the appropriate COBOL command for generating the source to object code (.obj), for example: cobol MYMODULE .CBL DEFAULTBYTE"00" CASE: Note that routines should be compiled with the DEFAULTBYTE "00" CASE compiler directives. Update the setting of the CHANGERS variable to add your masking routine name.
2	Update DE_CHANGERS.DEF.	Add an entry for your masking routine at the end, using a unique value, for example: `MYMODULE @101`

Step

Details

Update the build.bat script.

Add the appropriate COBOL command for generating the source to object code (.obj), for example:

cobol 
						   
						  MYMODULE
.CBL DEFAULTBYTE"00" CASE:

Note that routines should be compiled with the DEFAULTBYTE "00" CASE compiler directives.

Update the setting of the CHANGERS variable to add your masking routine name.

Update DE_CHANGERS.DEF.

Add an entry for your masking routine at the end, using a unique value, for example:

MYMODULE @101

For UNIX platforms, update the build script by adding the appropriate COBOL command for generating the source to object code (.o), for example: cob -xc MYMODULE.CBL -C "DEFAULTBYTE(00) CASE"

Building COBOL Masking Routines

On Windows platforms build your COBOL masking routine by invoking build. On UNIX platforms, build your COBOL masking routine by invoking ./build.
