BETA BASIC NEWSLETTER No
BETA BASIC NEWSLETTER No. 1 Welcome to the first issue! (This is its second printing. A few errors - mentioned in Newsletter No. 2 - have been corrected.) The Newsletter is intended to provide hints, examples and advice on Beta Basic programming. We are keen to include contributions from readers - we have already collected quite a few. Each issue will also cover questions asked by users. (Previous correspondents will know we answer letters anyway - but this way points of general interest can reach a wider readership.) As new Betasoft products become available, we will inform you, without much "marketing blather- speak". (You know, all that "UNBELIEVABLE INCREDIBLE MEGA WONDER PROGRAM Stuff.) I suppose I had better introduce myself, since this is the first issue. Your Editor (i.e. ME) is Dr. Andrew Wright, former.: medical research scientist turned programmer, generally known as Andy. I wrote the Beta Basic program and manuals for Betasoft, so I should be able to handle most readers' queries. You may wonder what your fellow Beta Basic users are like. Judging from letters and personal contacts, most users are over 20, which makes them ancient on the Spectrum scene. Many are professionals - photographers, engineers, programmers, medics, etc. Some are retired, some are students, some are unemployed. More than you might expect live outside the U.K. In general, I would say they are the "crème de la crème" of Spectrum users - so lets have some nice contributions! Because long programs will fill up an issue quite quickly, the programming contributions we like best are fairly short. To be as generally useful as possible, these should often be in the form of procedures, with an example program that calls them. -
