The Clipper, Summer '87, manual makes the Autumn '86 documentation look. In Short: A dBASE compiler with advanced programming features and an open.

Contents • • • • History Clipper was originally created in 1985 as a for III, a very popular database language at the time. DBASE code changes it from interpreted code (i.e., ), which must be every time each line of code is executed, to (or pseudo-code), which uses a to process the compiled p-code. P-code is considerably faster, but still not as fast as the generated by native compilers. Clipper was created by Nantucket Corporation, and later sold to. On April 22, 2002 and GrafX Software announced they had reached a Development, Licensing, and Marketing Agreement for two of their software development languages -- CA-Clipper.

As the product matured, it remained a tool for many years, but added elements of the and, as well as, and the code-block (hybridizing the concepts of dBase, or -evaluation, and ), to become far more powerful than the original. Nantucket's Aspen project later matured into the native-code compiler. As of 2009, the Clipper language is being actively implemented and extended by multiple organizations/vendors, like from Alaska Software and, as well as (-licensed) projects like Harbour and Many of the current implementations are portable (,, ( and ), (32- and 64-bit), and ), supporting many language extensions, and have greatly extended, as well as various Replaceable Database Drivers (RDD) supporting many popular database formats, like, DBTNTX, DBFCDX (, SuccessWare and Comix), MachSix (SIx Driver and Apollo),, and more. These newer implementations all strive for full compatibility with the standard / syntax, while also offering OOP approaches and target-based syntax such as SQLExecute().

As of November 2009, the Clipper and are still active. Programming in Clipper A simple - application:? Escapement analyzer crack. 'Hello World!'

How I have joined HMG Family – A Story It was in the year 1990, I had seen a computer, first time in my life. I was a commerce student, studying in a 100+ years old school in my home town Sivakasi (famous for fireworks ), Tamilnadu, Southern part of India. I was studying +2 (12th and final year in school). Once, the exams were over, it was time to join a College.

Not to waste the exam holidays, one of my friends had asked me to accompany him for a part time computer course in a near by Polytechnic College. I told him, “Ok”.

We joined that course which was for six months, conducted on Saturdays and Sundays. I studied some basics about computers and languages like BASIC, Pascal, COBOL and an introduction to Lotus 1-2-3, Wordstar and dBase III Plus. After that I had joined a college and my main subject was Commerce. After finishing my Under Graduation degree in the year 1993, I had joined Chartered Accountancy Course.

And, once I had finished this course in the year 1996, I joined my brother to manage our family business. Even though there was a computer in our office, I was not allowed to touch that. The reason was, at that time, computers (AT 386) were costlier and one cannot take the risk of losing precious data and computers were operated only by computer professionals. In the year 1997, I had purchased a computer on my own, and started implementing something which I had studied some seven years back. I had studied under the DOS environment and I had got Windows ’95 in my new system as my operating environment. Even though it was easy to operate, I could not do any programming. I had so much of works before hand and I was involved in them for about 1 year.

It was a Costing project in Excel with about 150 sheets, everything interlinked. It was a nice experience. I had done some macro programming in Excel for introducing thousand’s comma according to Indian tradition. In the year 1998, the computer professional who had programmed for the accounting, invoice processing and payroll processing for our business firm had gone for a better job. We could not create new reports according to the requirements and we had to play only with the old options. Only at that time, I had realized about the importance of Database programming.

Having the knowledge of DBase III+ programming, I had started to write small utilities to take self configured reports from the existing tables. I had the reference of the source codes for the existing software. It was done in Clipper Summer ’87 version. There is a saying, ‘Necessity is the mother of invention’. Necessity had driven me to do more and more programming. Actually, I had started staring huge prg files with various do while.not. Eof() loops and virtually indefinite nested if endif conditions.
