- COMPUTER EDUCATION PRODUCT REVIEW: CA-Clipper Basics: A Samples Disk
- AMULET Consulting
- ----------------------------------------------------------------
- Review by: Jason Yip
- Singapore Economic Development Board
-
- The CA-Clipper 5.2 application development product from Computer
- Associates, Inc. (the world's 2nd largest software company) is globally
- recognized as the premier programming language for serious database
- developer's for the DOS platform. Although CA- Clipper has its roots in
- the Xbase industry, once being solely a dBASE III compiler, the product
- has matured over the years to be a very respected alternative to the C
- language for developing desktop computer applications. However as with
- C, the learning curve is often steeper than many would hope for. I'm
- glad to report there is now a product that is directed specifically at
- beginning Clipper developers.
-
- AMULET Consulting has recently begun shipping a disk based educational
- product that eases the transition towards professional CA-Clipper
- programming. The "CA-CLIPPER BASICS: A SAMPLES DISK" product contains
- hundreds of code samples and application components that exhibit ways to
- use CA-Clipper's most difficult to understand features such as ragged
- array, code blocks, user defined commands (UDCs), scope and lifetime
- rules, predefined classes such as TBrowse and TBColumn, direct file
- access, memo fields, etc.
-
- The samples disk was originally marketed as a companion disk for the
- 1994 computer book "CA-Clipper 5.2 Step by Step", published by John
- Wiley & Sons, Inc. and written by Dan D. Gutierrez, AMULET's president.
- This book was based primarily on Mr. Gutierrez' monthly column appearing
- in Data Based Advisor magazine entitled "Clipper Basics." Mr. Gutierrez
- now writes the "Hardcore Clipper" column also for DBA. He also conducts
- a CA- Clipper on-site corporate seminar series, "The Clipper Expert
- Series" and teaches Clipper programming for UCLA Extension. A world
- class expert in the field of Clipper programming, Mr. Gutierrez
- regularly speaks at industry conferences both in the US and abroad.
-
- The samples disk is arranged by "chapter" where each chapter represents
- a different CA-Clipper topic matter. Here is a complete list of topics:
-
- Chapter 1: The CA-Clipper Development Environment, linkers, etc.
- Chapter 2: Basic Language Components
- Chapter 3: The Preprocessor
- Chapter 4: User Defined Commands
- Chapter 5: Subprograms, including scope and lifetime rules
- Chapter 6: Codeblocks
- Chapter 7: Arrays
- Chapter 8: Database Access, including RDDs, the Order Management
- System
- Chapter 9: Memo Fields
- Chapter 10: Object Based Technology
- Chapter 11: TBrowse
- Chapter 12: Direct File Access, the F* functions
- Chapter 13: Applications, data entry and reporting
-
- I have reviewed the code on the disk and have found it to be in
- excellent form. All the code has been thoroughly tested and the coding
- style is world-class. The best way to benefit from the samples disk is
- to print out one large code listing book and use the debugger to try out
- the samples, analyzing the results as you go. After getting through each
- example, I can safely say, you'll be a CA-Clipper programmer.
-
- The bottom line is, if you're already a dBASE programmer or a programmer
- still using the Clipper Summer '87 release (the release prior to Clipper
- 5), then this samples disk is a perfect way to get up to speed with the
- current release, 5.2d (as well as the soon-to-be-released version 5.3).
- It is also a good way to prepare yourself for the upcoming Windows based
- product from CA called CA-Visual Objects.
-
- The samples disk is available on a 3.5 or 5.25 inch high density floppy
- disk and costs $19.95 plus $5.00 shipping and handling ($24.95 total
- cost). California residents please add 8.25% sales tax. Orders with
- personal or company checks can be mailed to AMULET Consulting, P.O. Box
- 241713, Suite 21, Los Angeles, CA 90024. International orders please
- remit in US funds.
