צסדדג«בנל¢¢¢SPEED is a short m/l program that¢allows you to adjust the speed in¢which programs print to the screen¢(through the E: device only!) This¢should only affect BASIC, DOS¢M/L programs that use the CIO¢to print text. Some programs may¢use their own handlers, or put¢characters directly to the screen,¢and won't be affected by SPEED.¢¢f you use SPEED with a program¢that resets the keyboard vector,¢such as the T:EDIT program, you¢will probably have to re-load SPEED¢back into memory. You maybe able to¢press RESET to recover, but then¢you may lock your computer up!¢¢To use this program, LOAD it from¢DOS. If you are using SPARTADOS,¢just enter SPEED.¢¢To control the speed of the output,¢enter CTRL/SHIFT ##, where ## is¢a number between 0 and 9. 0 is¢the slowest, and 1 is the fastest.¢Pressing CTRL/SHIFT CLEAR, will¢return the printing speed to normal.¢¢You may have to adjust the speed¢to get the one you want. I prefer to use 3, which gives the text a¢nice smooth. Each number increase,¢increases the delay value by 25.¢A CTRL/SHIFT 1 has a delay value¢of 25, CTRL/SHIFT 2 has a delay¢value of 50, and so on. CTRL/SHIFT¢0 has a delay value of 255.¢¢To control the speed of the output¢through a program, just poke the¢delay value you want into location¢8254 ($203E).¢¢That's all there is to SPEED. It¢takes up 193 bytes and resides¢in memory from 8192 ($2000) to¢8385 ($20C1). It automatically¢traps the reset vector, and adjusts¢the memlo pointer ($2E7) to¢protect itself.¢¢SPEED.ASM is the source listing¢for SPEED, and can be located just¢about anywhere. It was written¢using the SynAssembler, so you¢may have to modify the program to¢work with other assemblers. I did¢not provide any documentation,¢so you'll have to leave me some¢E-Mail if you have any questions.¢¢¢ Glenn Smith¢ 70357,1136¢¢¢::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
