What is Electronic Engineering how to become a good Electronic Engineer ?

Editor — Thu, 05 Aug 2021 05:42:14 +0000

Electronic engineering :

Electronics engineering is a designing order which uses non-direct and dynamic electrical segments, (for example, semiconductor gadgets, particularly transistors, diodes and incorporated circuits) to plan electronic circuits, gadgets, Microprocessors/Microcontrollers and frameworks including VHDL Modeling for Programmable rationale gadgets and FPGAs.
The control regularly additionally outlines inactive electrical parts, typically in view of printed circuit sheets.

How to Become a good Electronic Engineer

The first and most thing you should do as a starting step to be a professional engineer, is to get a degree in electronics and communication.
If you want to be a professional engineer in Embedded System design or VLSI design (two most prominent field of electronics), there are institutes like CDAC, Vector India, VEDAIIT, Maven Silicon and many more which offer short term or long term courses in these fields. Not only that you also get the advantage of being placed in any leading electronics company.
If you want to be a professional engineer in PCB designing, you need to have good working knowledge on design tools like CAD, ORCAD, and Eagle etc. You even need to have basic knowledge about PCB designing and mounting.
If you want to be a professional engineer in VLSI or chip designing, you must have working knowledge in tools like Xilinx, Magic etc and of course must have good VLSI programming skills.
It is not only the knowledge of software tools that can make you a professional engineer, but also good technical skills.
These skills can be having practical knowledge in circuit mounting, soldering or PCB designing , practical knowledge in installation of networking products like routers, switches etc, practical knowledge of working with home automation devices like PLCs or practical knowledge of operating electronic equipments like Oscilloscopes, Wave Generators, Pulse Generators etc.
As a fresher, you can apply for the position of trainee or intern at any reputed company. If you are GATE or NET qualified, you can always apply for the position of research fellowships at any Government recognized research institutes.
A fresher with good theoretical knowledge about subjects related to electronics and communication can also opt for being a technical writer in the field of electronics and communication. Remember this might prove to be a great asset in increasing your exposure to the field of electronics.

What is the difference between comp and comp-3 usage ?

Editor — Mon, 19 Jul 2021 10:08:14 +0000

Comp :

COMP is 2 bytes.
COMP is used for Binary Representation it allows only S and 9.
COMP stores the data in the binary format.
With COMP fields, you have to drag out a calculator and convert the hex value to find out the true value that is being used in a program.
Memory usage is,

Comp-3

COMP-3 is 8 bytes.
Comp-3 is used for Packed Decimal values it allows S 9 V mostly it is useful for Decimal Calculation Values.
COMP-3 stores the data in the BCD(Binary Coded Decimal)format.
It is used to avoid rounding issues that occur when binary numbers are used to represent decimal fractions.
This is particularly vital in systems that method massive volumes of economic transactions/amounts
Memory usage is

Example :

Banking, Credit cards, etc.

Other cobol usages :

The usage clause specifies how the data item being stored internally .If no usage clause specified , the default usage clause would Usage is display

I have recorded a test over web application (with IE6.0) in analog mode. But, while running it my test gets failed. Why ?

I have recorded a test over web application(with IE6.0) in analog mode. But, while running it my test gets failed. Why ?

Analog mode records depend on screen as well as followed window.
It means if you record related to screen then it basically depends on position of the window.
While recording if you place window somewhere else and while running script you might be moved the window somewhere else. That’s why script is failing.

What is an AICA abend ?

Editor — Tue, 13 Jul 2021 06:19:45 +0000

What is an AICA abend ?

A task has been executing for longer than the runaway time interval (defined by the ICVR operand on the system initialization table macro, DFHSIT) without giving up control.
The runaway task condition indicates a possible loop in the application.

System Action

The task is terminated with an AICA transaction dump.

What is an AEY9 abend ?

Editor — Tue, 13 Jul 2021 06:15:40 +0000

The AEY9 abend can occur for the following reasons :

An EXEC CICS command has been issued that is not supported by the EXEC interface program DFHEIP.
A transaction has issued an EXEC CICS command which is supported in principle by the EXEC interface program DFHEIP, but for which the prerequisite function has not been included in the current CICS start-up.
A non-CICS command has been issued by an application stub (expansion of a DFHRMCAL macro), and the program DFHERM has detected that the required non-CICS support is not available. For example, an attempt to access DB2 when a DB2CONN resource is not enabled results in this abend.
An attempt has been made to use remote resources, but the local SYSID has been specified in an EXEC CICS command, or vice versa.
An attempt has been made to use remote resources, but ISC is not supported.
An EXEC CICS command contains an invalid AID or CONDITION identifier. This abend indicates that the EXEC CICS command has become corrupted.

System action

The transaction is abnormally terminated with a CICS transaction dump.

Module

DFHEIP, DFHEEI

What is the use of DSECT parameter in BMS ?

Editor — Tue, 13 Jul 2021 06:11:51 +0000

What is the use of DSECT parameter in BMS

DSECT is the parameter used for creating a symbolic map.

The TYPE=DSECT assembly is used to produce a series of data structures, collectively called the symbolic map set.
The output of a TYPE=DSECT assembly is a series of data structures, coded in the source language specified in the LANG option. There is a structure for each map used for input, called the symbolic input map, and one for each map used for output, called the symbolic output map.
Symbolic map sets are used at compile (assembly) time. You copy them into your program, and they allow you to refer to the fields in the maps by name and to pass the variable data in the form dictated by the physical map set.
Symbolic map sets are typically stored in the library your installation defines for source code that gets copied into programs. Member names are typically the same as the map set names, but they need not be.
You need the TYPE=DSECT assembly before you compile or assemble your program. You can defer the TYPE=MAP assembly and link-edit until you are ready to test, because the physical map set is not used until execution time. But, you must do both eventually, many installations provide a cataloged procedure to do this automatically.
The procedure copies the source file for the map set and processes it once using TYPE=MAP and again using TYPE=DSECT. You also can use the SYSPARM option in your assembler procedure to override the TYPE value in a particular assembly.

BMS

BMS is known as Basic Mapping Support. An application consists of formatted screens which act as a link between the terminal and the CICS programs. For communication to occur between the terminal and the CICS programs, we use CICS terminal input/output services. We use BMS to create screen designs with proper positions and attributes. Following are the functions of BMS,
- BMS acts as an interface between the terminal and the CICS programs.
- The design and format of the screen is separate from the logic of application.
- BMS makes the application hardware independent.

When you do a START, what will the value of EIBCALEN ?

Editor — Tue, 13 Jul 2021 06:06:21 +0000

When you do a START, what will the value of EIBCALEN ?

Value of Eibcalen=0

EIBCALEN

In this CICS reserved word we use usually in the subroutine, that say, we are calling a sub-program, and passing some data.
We don’t know whether data is received or not. So, I am getting some data from the screen passing to first main program and next to sub-program. With this variable we can test it and control the program logic.

EVALUATE TRUE

     IF  EIBCALEN = 0

           EXEC  CICS

           RECEIVE  INTO(WS-RECORD)

           END-EXEC

    END-IF

END-EVALUATE

And, we can continue writing the code, If EIBCALEN = 1 to throw abend.
