ETMxxx 300Mhz Single Bd. Computer /Pent. Slot1 -11 is a software package designed to provide RT-11, RSX-11M, RSX- 11M-PLUS, and ETMxxx 300Mhz Single Bd. Computer /Pent. Slot1 /E applications programmers access to the plotting capa- bilities of Digital's ETMxxx 300Mhz Single Bd. Computer /Pent. Slot1 graphics lineprinter. Using the PLXY-11 graphics subroutines, programmers can create software that prints out representations of data in graphs and charts with clear alphanumeric labeling. This makes PLXY-11 useful for equipping scientific, engineering, statistical, and econo- metric application programs with graphics. To use ETMxxx 300Mhz Single Bd. Computer /Pent. Slot1-11, the programmer writes FORTRAN programs that call the appropriate subroutines in the ETMxxx 300Mhz Single Bd. Computer /Pent. Slot1 -11 library. These subroutines convert the program's graphics requests into a series of vectors stored in an intermediate file. This file is submitted to the ETMxxx 300Mhz Single Bd. Computer /Pent. Slot1-11 postprocessing task, which converts its vector data into raster format suitable to the LXY12 graphics lineprinter. The user then transfers this converted file to the graphics printer via a standard file transfer utility such as ETMxxx 300Mhz Single Bd. Computer /Pent. Slot1, where it is printed out by the system ETMxxx 300Mhz Single Bd. Computer /Pent. Slot1 line- printer driver. ETMxxx 300Mhz Single Bd. Computer /Pent. Slot1 is shipped with the LXY12 graphics lineprinter and must be specified when ordering hardware.
