ISPF Dialog Developer
(Formerly called TSO ISPF Dialog Manager.)
| Duration: 5 days |
| Participants: Application programmers, developers, systems programmers, and systems support. |
|
Objectives:
Upon successful completion of this course you will be able to:
- Design, code, test, debug, and implement typical business-related dialog applications for TSO/ISPF. - Design, develop, and implement user-friendly menu selection panels, input/output display panels, pop-up window panels, and action bar (drop-down) menus. - Display short and long messages, and tutorial, table of contents, index, and help panels. - Use dialog services within CLIST, REXX, COBOL, and PL/I programs. - Create temporary and permanent tailored output files using file tailoring. - Create dialog tables; add, modify, and delete table entries; sort table rows; allow users to interactively update tables; and use TBDISPL to display and process multiple rows. - Use dialog library management services to manage physical sequential datasets, partitioned datasets, and members. |
|
Overview:
- This course teaches you how to create full screen panels for REXX, CLIST, COBOL, and PL/I programs. You learn dialog variable management, library management, table management, file tailoring services, library management services, etc. - System design and function interfaces are covered as well as other ISPF application topics. You also learn to develop Edit Macros for View and Edit screens. |
| Prerequisites: Solid knowledge and experience using TSO ISPF/PDF panels and good programming ability in REXX or CLIST is required. |
| Format: Lecture and hands-on computer workshops. |
