AUDIENCE:   System Programmers, Technical Support and Software Programmers and Advanced Application Programmers who need the ability to write and debug Assembler Language programs and better understand the software that their installation uses. PREREQUISITES:   When attending this Advanced Assembler course, the assumption is that the person attending will be very familiar with the instruction set as outlined in the first Assembler course. Advanced Assembler starts with the understanding that the first course's instruction set is understood. The material in Advanced Assembler has substantially increased, which includes all the new instructions that IBM has made available. Listed below is the instruction set that we have traditionally covered. Also, the new instruction set has been added to this list. Most of the course time will be handling the remaining instructions that were not discussed in the first course and the new instruction set. DURATION:   4 Days APPROACH:   This class is taught by lecture with hands-on workshops. OBJECTIVES:   Develop a better understanding of the machine and how it processes instructions. Develop the skill to write assembler programs, particularly those small functions which will increase the efficiency of their corporation's computing throughput. Gain a practical introduction to the essential operating system interfaces with Assembler. Enhance their diagnostic skills. Improve their dump analysis skills. Enhance their ability to use advanced management services. Enable themselves to code their own macro definitions Enhance their knowledge of Channel Programming and how it works Improve their programmers design abilities COURSE CONTENT:   CONTROL SECTION Source Code Definitions; Object Modules, and Load Modules Control Section Definition START Command Definition CSECT Command Definition Setting up Addressability in a Control Section USING Statement BASR Instruction (Branch and Save Register) Multiple Base Register Specifications MVC Move Character Instruction LA Load Address Instruction Symbolic Address Base Addressing Displacement Calculations Index Addressability MVI Move Immediate LITERALS EQUATES DATA DEFINITIONS Define Constant Binary Characters Hexadecimal Fixed Point Decimal Floating Point Addressing Operand Subfields, Length Attributes, Constant Alignment, Padding, Types, Duplication Factor Expressions, Bit Length Modifier, Y CONS, A CONS, S CONS, V CONS and Q CONS Define Storage INSTRUCTION SET LH: (Load Half Word) LR: (Load Register) ST: (Store) STH: (Store Halfword) LTR: (Load and Test) C: (Compare) C: (Compare Halfword) CR: (Compare Register) BCT: (Branch on Count) BCTR: (Branch on Count Register) BAL: (Branch and Link) BALR: (Branch and Link Register) CVB: (Convert to Binary) CVD: (Convert to Decimal) UNPK: (Unpack) AH: (Add Halfword) SR: (Subtract Register) SH: (Subtract Halfword) MH: (Multiply Halfword) M/MR: (Multiply) D/DR: (Divide) AP: (Add Decimal) SP: (Subtract Decimal) MP: (Multiply Decimal) DP: (Divide Decimal) ZAP: (Zero and Add) CP: (Compare Decimal) SRP: (Shift and Round Decimal) ED: (Edit) EDMK: (Edit and Mark) ALR: (Add Logical) CLR: Compare Logical CDS: Compare Double and Swap CLR: Compare Logical CLCL: Compare Logical Long CUSE: Compare Until Substring Equal EAR: Extract Access IPM: Insert Program Mask LAM: Load Access Multiple LNR: Load Negative MC: Monitor Call MVN: Move Numeric MVPG: Move Page MVO: Move Offset SRST: Search String SPM: Set Program Mask STCK: Store Clock TS: Test and Set UPT: Update Tree CFC: Compare and Form Codeword CS: Compare and Swap BAKR: Branch and Stack CLM: Compare Logical Under Mask CLST: Compare Logical String CPYA: Copy Access ICM: Insert Character Under Mask LAE: Load Address Extended LCR: Load Complement LPR: Load Positive MVCIN: Move Inverse MVCL: Move Long MVST: Move String MVZ: Move Zone SAC: Set Access STCM: Store Character Under Mask SVC: Supervisor Call SLR: Subtract Logical CLC: Compare Logical Character B: Branch Instruction Format CLI: Compare Logical Integer STM: Storage Multiple IC: Insert Character STC: Store Character L: Load LH: Load Halfword LR: Load Register SH: Subtract Halfword ST: Store LTR: Load and Test LCR: Load Complement DSECT: Dummy Section   -How to Define a Dummy Section.   -What a Dummy Section Is.   -How to Use a Dummy Section.
