The ASCII converter uses only ASCII text floating point numbers. Thus, 15.0 is represented as "15.0" or "1.5E+1" or "15." Each number must end with a delimiter which may be a comma, blank, carriage return, line feed, or form feed. Multiple delimiters are allowed between numbers. An optional 80-character comment line is available. Comments must be placed immediately after the resolution value and before the first Y value, and they must be preceded by an apostrophe. The comment string is not supported on export. The number of points must be an integer to avoid a rounding error. The Control-Z end of file marker is NOT required. This format is easy to set up from Array Basic and almost any other programming language. ASCII data files should have a .ASP file name extension. They are set up as follows:
Type Meaning
Text Number (Integer) Number of Y values
Text Number First point's X value
Text Number Last point's X value
Text Number Type of X values - see Appendix A
Text Number Type of Y values - see Appendix A
Text Number Resolution of data
Text (or Text Number) Comment line (optional)
Text Number First Y value
Text Number Second Y value
...
Text Number Last Y value
The first six values may all be set to zero during import, but must be present in the file even if they are unused. The ASCII converter uses the actual number of data points found in the file if the first value is zero. | |
