Find out the rest of the story about PRGDLTRCDS and Watch considerations.
By Bruce Vining
This is the sixth in a series of articles on detecting that certain messages have been sent on your system and then making processing decisions based on those messages. The underlying technology, known as Watch support, became available with V5R4.

Learn more ways to use exit programs for the Watch for Event exit point. By Bruce Vining This is the third in a series of articles on watching for certain messages on your system and then making processing decisions based on those messages. The underlying technology being used is known as "watch" support and became available with V5R4. In this article, we will look at how to automate the re-enabling of a specific *USRPRF when the *USRPRF has been disabled because of too many invalid password attempts--that is, the number of signon attempts has exceeded the QMAXSIGN system value. |

Write an exit program for the Watch for Event exit point.
By Bruce Vining
This is the second in a series of articles related to watch support on the system. The previous column, "One Approach to System Automation," introduced the concept of watches and the Start Watch (STRWCH) command. Also provided in that article was the source for a watch exit program that would be called when the message CPD1689 (Local system time has been adjusted) was sent to the QHST history log. We did not, however, have time to discuss the mechanics of how the program worked. In this article, we will look at the actual program flow.

Learn how to use watch support to automate system operations. By Bruce Vining Over the last several months, I've received many notes from readers, including these: - I have some custom routines that need to run when a Daylight Saving Time change goes into effect. How can I have these programs run automatically?
- There is one user profile that the system operator is always re-enabling.... Is there a way to automate this?
- We have a program that periodically reads QHST files to see what files need to be reorganized...maintain record sequence...based on CPF4653.... Is there a way to avoid scanning QHST?

Find out the rest of the story about the User Application Information APIs. By Bruce Vining In the last column, we saw how to use the Update User Application Information API to set default values for a new user of the RPG_DEVELOPER_MY_APPLICATION application. Today, we will look at how to combine the Update API with the Retrieve User Application Information API in order to provide application awareness of past user preferences. |

It's easy with the User Application Information APIs! By Bruce Vining I received the following from reader Kiernan M.: "Your articles are giving me all kinds of ideas for improving our system.... Is there an API that lets me recall previous usage information like how SEU does with *PRV?" As this would be an extremely short article if this capability was unavailable, it's safe to assume that there are indeed APIs to assist you in retaining previous usage information. |
