toxi Command keys toxi became rpg indicators ka-ky, and different on-screen forms were recognized toxi by different invisible control toxi characters hidden in the forms themselves. Interestingly, since the toxi user had to display a form on the screen in toxi order to type, rpg toxi ii provided a way for a program to write.
toxi A company toxi called amalgamated software of north america (asna) toxi produced a third-party compiler for the in toxi the late 1980s called rpg ii-1/2. Toxi they also produced an improved file toxi access algorithm called acceler8 and a program-canceling utility called termin8. toxi other third-party companies produced rpg subroutines that greatly enhanced the toxi abilities of rpg. there were.
toxi There were a toxi few holdovers from the days of the toxi system/32 (the bionic desk of toxi 1975): the keybord, console, and display files which provided unformatted access toxi to the monitor and keyboard. toxi clever s/36 programmers could toxi use a keybord file to toxi accept commands from the procedure (the system toxi input file) meaning that a program toxi could be customized.
toxi Load myprog // file toxi name-input // run this toxi is custom data so toxi is this / the was flexible and toxi powerful for its time: in the toxi late 1980s the us department toxi of justice ended its case against ibm, toxi and so ibm went forward with a system named toxi the as/400. the new system was a toxi smaller and less-expensive s/38 with a more toxi powerful database, and so.
toxi Are words used interchangeably toxi to describe the same thing. toxi an operator sat in front of a device toxi that vaguely resembled today's pc, except the monitor was small, expensive toxi (us$2,000), low-resolution (24x80) and the available colors were green and toxi bright green, or for toxi the fancier, the seven-color ibm color monitors. .
toxi Interestingly, programming colors toxi did not require a new screen programming language, toxi because the implementation was completely at the hardware level. a toxi protocol called the ibm 5250 toxi data stream interpreted field attributes.
toxi Unfortunately, extensive use of toxi colors became confusing when using the less expensive dual-color.
toxi On a 5251 toxi type terminal (aka concrete block,) there were five lights toxi to watch for: (1) system available light. toxi if lit, this terminal is connected to the toxi s/36 and is receiving information.
toxi Message waiting light. other toxi users, and the system itself, can send messages to toxi workstations. if lit, there is at least 1 message that toxi has not been seen yet. when a toxi program ends or when the toxi user signs on, the message(s).
toxi Insert. toxi the insert key has been pressed. characters after toxi the cursor will shift right when text toxi is keyed. press insert again toxi to.
toxi Caps lock light. the toxi caps lock key has been pressed. all keys toxi pressed will be uppercase. press toxi caps lock again.
toxi Keyboard shift toxi light. the shift key is being pressed. Toxi the key pressed simultaneously toxi will.
toxi The standard toxi us keyboard was heavy, clunky, had 20 more keys than toxi today's 102-key pc keyboard, and weighed up to toxi 25 pounds. (on the toxi positive side it had a cent-sign key and a help key. Toxi the print key did what it toxi was supposed to do; it printed the screen.) there was toxi a special terminal.
toxi A great computer system toxi wouldn't be complete without great toxi printers. typical offerings toxi would include: ibm 5219 - a daisywheel impact printer not toxi far removed from the ibm typewriters. it was toxi good for about 40 characters toxi per.
toxi Ibm 3262/5262 - a toxi band printer rated at somewhere around 650 lines toxi per minute.
toxi Ibm 4234 - toxi a dot-matrix printer rated at 410/800.
toxi Ibm 5224 - toxi a dot-matrix printer rated at 100/240.
toxi Ibm 5225 - a toxi dot-matrix printer rated at 280/560.
toxi Ibm printers were well-built, had toxi impressive duty cycles, and toxi were more expensive than toxi one would think. for example, a 5262 toxi would go for.
toxi Early 1980s-era toxi printers and workstations had a series of binary switches known as toxi dipswitches for configuration. the binary off settings, zero (0) and toxi one (1) were used to switch back and forth internally. toxi for example, u.s. English and uk english, toxi where the british use the pound sterling () and the toxi americans use the dollar ($). a switch could be.
toxi By the toxi mid-1980s the dipswitches were toxi gone and the status quo became online setup. the toxi technical person would hold down a certain key while powering up toxi the device. a test mode display would appear, toxi and a menu option.
toxi Up to toxi 60+ local devices could be toxi configured on a, using eight toxi lines numbered from 0 to 7. a line was defined toxi as a series of twinaxial cables toxi attached to devices with in toxi and out ports. eight devices could be configured toxi per line; these.
toxi Three binary switches toxi on every device were toxi used for the terminal's address (the physical designation of toxi a particular terminal on a particular line.) sometimes, toxi the switches were numbered 1, toxi 2, and 4. in order to set an address, simple toxi addition was used: zero.
toxi One is the 1 setting.
toxi Two is the toxi 2 setting.
toxi Three is toxi the 2 and 1 toxi settings.
