A large part of this two week workshop style course is spent writing and testing Assembler programs, a minimum of ten in fact! Experience of another programming language or a good technical background with the equivalent of JCL and MVS concepts are ideally required.
 IBM System 370 | Representation of information; Operand addressing; Machine code instruction formats |
| Assembler Layouts and standards | |
| Defining Data areas | |
| Standard/Decimal Instructions | |
| Program Structure | Implementing and controlling loops; |
| Subroutines | Good practices |
| Program Linkage | Conventions; The calling program; called program; Passing parameters; Save areas |
| Input/Output | Macros; Open; Close; Get; Put;DCB |
| Debugging | Assembler listing;Link edit listing; Save areas |
Senior programming staff and systems programmers with a solid technical background with an in-depth knowledge of Assembler are likely to find this course informative and challenging (some very experienced PL/1 or COBOL programmers could gain some benefit by attending). Over the three days the theory is consolidated by several dumps and practical exercises.
| Overview | Compilation or Assembly listings; linkage Editor maps |
| Control Blocks | Function and use; Types of queues used; |
| FIFO; LIFO; Priority | |
| Open & Close Processing | Forward/reverse merge; Open exits; |
| DEB; DCB;JFCB;DSCB;Open failures | |
| Task management | ASCB; TCB; PRB; SVRB; |
| Contents Supervision | CDE; LLE; XL |
| Interrupt Processing | Save registers & PSW |
| Storage Management | Control Blocks; Obtaining/releasing storage; Subpools |
| Data Management | I/O processing; Control Blocks; Channel programs; I/O Errors |
| Asynchronus Exits | Routines, Addressability & Save areas; IRB; Potential errors |
Systems programmers and programmers who may be required to write or maintain macros will gain an in-depth knowledge of the whole concept of macro writing by attending this two course, which consists of a series of carefully designed practical exercises.
| Facilities | Syntax; Macro statements (header, prototype, model, trailer) |
| Symbolic Parameters | Positional and Keyword; Sublists; & SYSLIST |
| Set Symbols | Arithmetic; binary; Character; Local; Global |
| Attributes | Type; Length; Scaling Integer; Number; Count |
| Conditional Assembly | Sequence symbols; Conditional/Unconditional branch instructions |
| Additional Features | System Variable symbols; Substrings; Arrays; Macros within macros; MNOTE & MEXIT |
| Design | Tips and techniques; Conventions used in IBM supplied macros |
An intensive course, built expressly around your own training requirements for new entrants to data processing who wish to become programmers, or who need a programming background before moving into analysis. The course can be anything from 4 to 12 weeks, depending on the level of expertise required. Extensive use of case studies will give the students a practical working knowledge of Assembler Programming.
