ProCal10 enables the production of Calendars in any of ten formats either to a colour printer (preferably a laser printer) or by using Adobe Acrobat Distiller to enable process colour separations to be saved as a PostScript file for offset printing. ProCal10 has been written for Windows using PB/WIN (© PowerBasic Inc.) and EZGUI35 (© Chris Boss). The program should work in Windows operating systems from Windows XP upward with a minimum 64mb RAM. It has been written to suit a 1024 x 768 pixel display but will work on 800 x 600 display. Pictures used are in bitmap (*.bmp) format but ProCal10 automatically converts JPG, TIF and GIF pictures and saves them in bitmap format. ProCal10 is fairly simple to use, either commercially or privately, to produce Calendars with an advertising or personal message and include pictures for the year or each month. Installation ? ProCal10 comes in three files to be installed (unzipped) into one directory (or folder) ? preferably ?c:calendar? ? on your computer. A number of sample calendar (*.txt), message (*.rtf), holiday (*.lst) and events (*.spc) files are included for demonstration purposes. ProCal10.exe is the main operating file. Ezgui35.dll is a dynamic link library for the runtime. Helpfile.rtf is the Help File text used in ProCal10.
