SCalc is a simple spread sheet program. The user interface applies the UNIX curses library for control of a terminal screen in text mode. This program was developed using the GNU C++ compiler and related tools. Limitations in SCalc -- The screen does not scroll. The entire spread sheet is the size of the terminal screen with five columns, A to E, and nine rows 1 to 9. -- Numbers are double precision floating point and are displayed in scientific format or in floating point format. -- Column widths will are fixed at 14 spaces. Text that exceeds the column width is clipped in the cell view. Numerical data in scientific format should always fit this space. -- The user cannot copy from cells to other cells, insert or delete lines or columns, of change cell widths. Some features of SCalc -- Built in mathematical functions abs, cos, ln, exp, ... -- Features for saving and loading spread sheets to and from disk -- Capability to clear spread sheets -- Features for automatically or manually re-calculate cell values
