List of keywords

Each .LOG data file is split in several paragraphs that contains data sets of the same nature (for example wave characteristics, convergence parameter, ... ). Each paragraph consists in a number of keywords possibly followed by one or more free format numerical data lines. Some keywords are mandatory while others are optional.

Unless otherwise mentioned, the order of appearance of the various keywords (and their related data) is arbitrary, except for the STOP or EXEC commands that must logically conclude the data set.

  • Keyword cards : Each keyword begins with a "*" character in the first column.

  • Comment cards : Each comment line must begin with a "C" character in the first column. Comment cards may consist of any 80 characters alpha- numeric text. Comment cards may be freely interspersed through the input data file. They are merely echoed back by the program without being subject to any other processing.

  • Free format numerical data cards : The separator is one (or several) blank space(s). The decimal point for floating point data without decimal part need not necessarily be typed in. Conversely, should a floating point field be input in place of an integer, then real to integer conversion would be automatically done through simple truncation of the decimal part.

  • End Of Line (EOL) : End of line is identified by the "&" character in any column. After this character any data on the same line is ignored and the next line is read.
