DATA BASE This utility program (printed over two weeks) was generated simply out of need and the fact that at the time I could find nothing similar at a realistic price.
My requirements were for a simple data base of names and addresses which I could access either as a group or individually and then print-out either to labels or a list. The Search and Delete routines were added as a means of quickly locating a particular file which needed to be amended or deleted without fuss whilst the Alphabetical Sort was added to tidy up the list I now keep all my names and addresses on this data base and intend to elaborate still further with telephone numbers, etc. At least it is a package which didn't cost me an arm and a leg and which I find was well worth the trouble to generate. The print-out to labels was designed for the 'single' label roll as I found these convenient, but little modification is re quired for the multiple labels rolls. Printer output was to an Epson printer MX 82F/T although for the purpose of this article I did not include an instruction to cancel the Step over Perforation which can be obtained by the integral switches on this machine. My own copy has this built in the label option routine and will be obvious by the make of printer used.
For individual addressing of envelopes by the printer, a simple TAB instruction is used to position the print head as required I included a variable X for my own use which could be set to tabulate for any envelope size. Note that the variable M has been set for 100 entries but this may be altered to suit. Also, the cassette has been used as a storage medium but disc storage may be used as required with slight modification to the output stream. Next week, the rest of the listing, plus a few brief program notes. In the meantime, for the impatient, tape copies of the program are available, at a cost of £2.50 Write to PO Box 17, Burnham on Sea, Somerset TA8 1DT. Popular Computing Weekly
