// PMVIEW.C -- A file browse program for the OS/2 Presentation Manager.
//
// Copyright (c) 1990 Ziff Communications
//
// Written by Douglas Boling
// Modified by K. L. Singer as follows:
// 1. Fixed bug when displaying ASCII bytes > 7F in Hex display.
// 2. Corrected to display found search string as top line of Hex display.
// 3. Added Hex string search option.
// 4. Corrected inability to scroll past 64K using vertical scroll slider.
// 5. Corrected random posiition in top line when using vert. scroll slider.
// 6. Added Hex offset and Line No. options in Search Goto command.
// 7. Corrected expanding of Tabs.
// 8. Corrected Hex display when jumping to/near end of file.
// 9. Modified End key to go to start of last line (ASCII)/16-byte para (Hex).
// 10. Corrected repeating lines of text between last CR and last byte of file.
// 11. Corrected to prevent scrolling of Hex display beyond end of file.
// 12. Added Hex-EBCDIC display option.
// 13. Corrected to ensure vertical scroll slider visibility in Hex display.
// 14. Corrected problem introduced by item 5.
// 15. Modified Open File Dialog to put name of viewed file at top of list box.
// 16. Corrected incorrect file name displayed in "Unable to open file" msg.
// 17. Added file name filter retention between Open File dialogs.
// 18. Added "New" item on File sub-menu to close file and leave PMVIEW active.
// 19. Changed shortcut key for Exit to Alt-X (from Alt-E) to conform to CUA.
// 20. Corrected handling of command line option for slash and upper case.
// 21. Added command line parameter /M to exclude Min. button from frame wndw.
// 22. Added mnemonic keys for all dialog box items.
// 23. Modified Open File dialog box to place file entry field at top of box.
// 24. Modified all dialog boxes to be centered, when possible, in client wndw.
// 25. Added capability to include wild cards in cmd line file name as filter.
// 26. Modified title bar and moved Searching... msg to box to conform to CUA.
// 27. Added on-line help facility.
// 28. Corrected window status to be active/focus when executed from CMD.
// 29. Added option to display file position at the bottom of the display.
// 30. Added hourglass pointer during waiting periods.
// 31. Added XGA support and selections for all OS/2 1.3 VIO font sizes.
// 32. Added ability to accept dragged and dropped file from OS/2 1.3 appl.
// 33. Added ability to accept dragged and dropped file from File Manager.
// 34. Fixed file position line scrolling into text area on non-VGA dsply.
// 35. Circumvented OS/2 1.3 XGA Driver bug and improved font list generation.
// 36. Corrected error recovery when Open File Name entered is zero length.
// 37. Added test for valid dragged object file name (from OS/2 2.0 WP/appl.).
// 38. Increased stack size for OS/2 2.0.
