1. 如果你不喜欢现在的工作，要么辞职不干，要么就闭嘴不言。初出茅庐，往往眼高手低，心高气傲，大事做不了，小事不愿做。不要养成挑三拣四的习惯。不要雨天烦打伞，不带伞又怕淋雨，处处表现出不满的情绪。记住，不做则已，要做就要做好。 ­

­
2. 每个人都有孤独的时候。要学会忍受孤独，这样才会成熟起来。年轻人嘻嘻哈哈、打打闹闹惯了，到了一个陌生的环境，面对形形色色的人和事，一下子不知所措起 来，有时连一个可以倾心说话的地方也没有。这时，千万别浮躁，学会静心，学会忍受孤独。在孤独中思考，在思考中成熟，在成熟中升华。不要因为寂寞而乱了方 寸，而去做无聊无益的事情，白白浪费了宝贵的时间。 ­

3. 不要像玻璃那样脆弱。有的人眼睛总盯着自己，所以长不高看不远；总是喜欢怨天尤人，也使别人无比厌烦。没有苦中苦，哪来甜中甜？不要像玻璃那样脆弱，而应像水晶一样透明，太阳一样辉煌，腊梅一样坚强。既然睁开眼睛享受风的清凉，就不要埋怨风中细小的沙粒。 ­

COBOL (COmmon Business Oriented Language)

History.

In 1952, Grace Murray Hopper began a journey that would eventually lead to the language we know as COBOL.

In 1959, an industry-wide team was assembled to formulate a common business programming language. The Conference on Data System Languages (CODASYL)  led by Joe Wegstein of National Bureau of Standards (now National Institute of Standards and Technology) developed a new language, and created the first standardized business computer programming language.

COBOL (Common Business Oriented Language) was developed under the auspices of the U.S. Department of Defense in cooperation with computer manufactures, users and universities. The initial specifications for COBOL were presented in a report of the executive committee of CODASYL committee in April of 1960.   It was designed to be a business problem oriented, machine independent and capable of continuous change and development.

1968 –  American National Standards Institute (ANSI) developed a standard form of the language  known as American National Standard (ANSI) COBOL. This was an attempt to overcome the incompatibilities of the different versions of COBOL.

1974 –  ANSI published a revised version of (ANSI) COBOL

1985 –  ANSI published another revised version

Today — ISO and ANSI committees have completed the features of the latest revision of COBOL 2002.

Title

Random Execution of Job Steps.

Abstract

This document provides a generic solution for execution of Job steps randomly without editing the JCL.

Problem Description

Executing the steps randomly in a job without editing the JCL is a tedious thing in Mainframes. Suppose for testing a program or JCL itself, we just want to execute some steps that are having changes but they are in the random order.

For example, the JCL given below having 4 steps STEP010, STEP020, STEP030 and STEP040, but if we want to test the XYZ program changes then we just need to execute the steps STEP020 and STEP040, and not STEP010 and STEP030.

So in order to test the changes in the program XYZ we can do either of the following.
