Both full travel and smooth face membrane keypads are available.Two slightly different key entry formats are utilized. Continuation Options are selected by striking a single key while dataentry requires the operator to select the data entry location, key in the data and finally strike the ENTER key to terminatethe entry process.DataEntryFormatThe data displayed on any screen can be changed by the operator if one of the Continuation Options is EDIT. This optionis selected by keying in the access code sequence .00 Access to the data can not be obtained if the DATA KEY is in theDATA LOCKED position. This data lock provides some security against unauthorized data access. Upon access to a datadisplay, a flashing cursor will be displayed on the screen at the location where the user may enter data. This cursor is aflashing square box the size of a single character and is located at the right edge of the current data entry location. Fordisplays with more than one data entry location this cursor can be moved to other data locations, without chanqinq anyofthedataonthescreen, by using the left (<-) and right (->) arrow keys. The left arrow key moves the cursor back (or left orup) through the data list whereas the right arrow moves the cursor forward (or right or down) through the data list.The ENTER and ESCape keys have special significance during data entry. When the user strikes the ENTER key heinstructs the computer to use the data value exactly as shown on the display. If a new data value has been keyed in, thenew data value will be used. If the originally displayed data has not been changed ENTER will not change the data.WYSIWYG -what you see is what you get-.The ESCape key allows the user to escape directly and immediately from this display to the previous display. Any newdata value in the process of being keyed but not ENTERed will NOTbe used; the previous data value will be retained.As a new data value is being keyed character by character, the left arrow (<-) can be used to delete the previous characterentry. The left arrow can be thought of as a correction arrow.The right arrow (->) will function exactly as the ENTER key.The minus sign will not be recognized unless it is the first character entry.Only one decimal point will be allowed per entry.The user should not be intimidated by the keypad. The operation of this keypad, the ENTER, ESCape and arrow keys ishighly intuitive. The computer will not allow the entry of unrecognizable key sequences. The operator is encouraged toexperiment with all the keys until he is familiar with their functions and comfortable with their use.page F - 103SYSTEMS Equipment Corp. 8/31/89 Page (55)
