Save Wave as General Binary

// SaveWaveAsGeneralBinary(pathName, filePath, dataType, byteOrder, w)
// Saves the wave's raw data only. This is of use to export to another program.
// This works on numeric waves only, not on text waves, DFREF waves, etc.
// NOTE: This overwrites the file if it already exists.
// Example:
//  Make/N=128/S jack = sin(x/8)
//  SaveWaveAsGeneralBinary("", "jack.bin", 0, 0, jack)
// This writes 4 bytes per point of single-precision floating point data for a total of 512 bytes.
