The screen image can be saved to disk for recall at a later date, and hard copies can be printed with a dot matrix printer.

PC MAP-MAKER allows users to more » view tabular data from US Geological Survey files such as WATSTORE (National Water-Data Storage and Retrieval System) in a map format in a time much shorter than required by sending the data to a line plotter.

Essentially any point defined by a latitude and longitude and any line defined by a series of latitude and longitude values can be displayed using the program. Data can be political boundaries such as state and county boundaries natural curvilinear features such as rivers, drainage areas, and geologic contacts and points such as well locations and mineral localities. PC MAP-MAKER is an ADVANCED BASIC program written to provide users of IBM XT, IBM AT, and compatible computers with a straight-forward, flexible method to display geographical data on a color or monochrome PC (personal computer) monitor. In addition, peek and poke routines, a routine that returns the address of any variable, and routines that can access the system time and date are included. SUBPAK is a function library which allows Microsoft FORTRAN programs to calculate random numbers, issue calls to the operating system, read individual characters from the keyboard, perform Boolean and shift operations, and communicate with the I/O ports of the IBM PC. These routines support both pixel coordinates and a user-specified set of real number coordinates. A set of line drawing routines is included for use with IBM`s Color Graphics Adapter or more » an equivalent board (such as the Enhanced Graphics Adapter in CGA emulation mode).
A routine to set the color of the characters that these routines display is also provided. The text mode routines allow the cursor to be placed at an arbitrary point on the screen and text to be displayed at the cursor location, making it possible to create menus and other structured displays. « lessĭISPPAK is a set of routines for use with Microsoft FORTRAN programs that allows the flexible display of information on the screen of an IBM PC in both text and graphics modes. A set of line drawing routines is included for use with IBM''s Color Graphics Adapter or more » an equivalent board (such as the Enhanced Graphics Adapter in CGA emulation mode). 7 refs., 4 = ,ĭISPPAK is a set of routines for use with Microsoft FORTRAN programs that allows the flexible display of information on the screen of an IBM PC in both text and graphics modes. The routines will also work on the IBM PC or XT in CGA mode, but they require more time and yield less resolution. These EZVIDEO routines give the IB, AT user a stand-alone capability to make useful scientific or engineering plots directly on the AT, using data generated in FORTRAN programs. This higher-resolution hard copy is adequate for most purposes because of the enhanced resolution of the screen in the EGA and VGA modes. Typical screen plots require about 10 seconds (s), and good hard copy of the screen image on a laser printer requires less than 2 minutes (min).
More than forty DISSPLA calls are simulated by the EZVIDEO routines. Screen dumps can also be made to an attached LaserJet or Epson printer to make hard copy without using terminal emulators. EZVIDEO simulates a subset of the well-known DISSPLA graphics calls and makes plots directly on the IBM AT display screen. These routines are written in FORTRAN and can be called from FORTRAN programs. A set of IBM PC-based FORTRAN plotting routines called EZVIDEO is described in this report.
