It is, well this program attempts to rescue you from this untidy mess. Notepad provides virtual sheets of paper stored on disc, the number of which depends on the format of your discs :- DFS 40T 3 X 26 = 78 DFS 80T 7 X 26 = 186 ADFS S 6 X 26 = 156 ADFS M 12 X 26 = 312 ADFS L 24 X 26 = 624 You need to prepare a blank formated disc for use with this program.This is done from the first screen on running the program. However there is a dummy file with two pages on this disc which may be used for test purposes. If you already have a prepared disc pop it in any drive and make this the current drive using the * command option, before running the main program. When first prepared, the pages are given a title that is their location in the notepad, this is displayed at the top of the page in blue initially Page A1 this will be temporarily overwritten with the help line. <H>elp <I>ndex <P>rint <['> <Esc> Use the cursor keys to navigate around the notepad. Index sets off an auto display of the whole notepad which may be stopped when it reaches the page which you wish to edit. Press <Return> to enter edit mode The help line will be replaced with the true top line and a large flashing cursor will be visable. Warning hitting <esc> from here will save the displayed page without prompt, so if you do not wish to save the changes you have made, use <Break> While in Edit mode the function keys are as the 8BS message system barring shift+f9 and ctrl+f9 which have the same effect as f9 i.e. pixel editing While in pixel editing a smaller flashing cursor is used. Also ctrl+P prints the page ctrl+C clears the page returning its initial title. Epson 9pin If you have an Epson 9 pin printer or compatible you may select this option from the first screen. When in this mode Teletext graphics characters used in the notepad are printed rather than being replaced with a space. Normal contiguous as well as seperated graphics are catered for, and also the square brackets are redefined as arrows so the printout is as displayed. On startup this option is set off but may be altered to on by changing :- 130epson%=0 to 130epson%=1 Then SAVE"NotePad"  From: K2K (Peter Davy) Program: LIST PRIME NUMBERS (D6E's program in Issue No.50) My interest in generating prime numbers goes back to my pre-computer days when I used to struggle to do it on a programmable calculator. Having seen in About this disk that there was a Prime Number program I went straight to it to see if there were any comments I could make. There were! With a few changes the program can be made to run very much faster. The principle of the program is to test each possible prime number to see if it has any factors apart from 1 and itself. If it has it can't be a prime number. Apart from 2, all prime numbers are odd numbers. In D6E's program the next possible prime number is derived by incrementing by 1. The number of possible primes to test can be halved by incrementing by 2. An odd number cannot be exactly divisible by an even number. D6E increments his divisors by 1. The number of operations can be halved again by incrementing the divisor by 2. Finally the biggest gain in speed of all. When searching for a factor of the possible prime number, it is sufficient to take the divisor up to the square root of the possible prime number rather than all the way up to the number itself. For example if 5197 (which is a prime number) is being tested, it is only necessary to try divisors up to 73 as the square root of 5197 is 72.090. It would be a waste of time trying 75, 77, 79, 81, ... etc. as if a factor above 75 exists we would have encountered the corresponding factor on our way up to 73. I found it easier to incorporate the above changes by re-writing the program. List Prime Numbers (2) is to be found elsewhere on this disk. Line 20 gets the primes 2 and 3 out of the way and the program proper starts at line 30 by considering 5 as a possible prime. Incidentally I usually consider 1 to be a prime number but for this exercise I have gone along with D6E and taken 2 as the first prime. An indication of the relative speeds: PRIME NUMBER D6E's prog.

CHAIN"£SIGN" when you're in BASIC to start it up.Answer the on screen question when prompted,and have your printer at the ready when prompted. Once printed you wil be asked to enter the two character numbers that appear in your wordprocessor files and printed wordprocessor files.The normal BBC pound sign as seen in Mode 7 for example is &60 (chr$ 96). The disk drive,or current media will then start and save a custom version of a patch to it.In future simply *RUN it to correct the problem. As the program is intended to be able to be run from BASIC etc... where complex VDU sequence such as palette or window definitions may be sent it will also handle these correctly. Hence VDU23,250,96,96,96,2,1,96,0,7 will be interpretted correctly even though it contains ` signs and printer sequences and nulls and bells. Let me know how you get on...
