Generator Input Files
The initial setup of a KEPLER problem is specified by a series of
instructions (known as
cards for historical reasons) that each
occupy one line in an input file termed a
generator file. (Or
sometimes a generator
deck for the same historical reasons –
backup versions of KEPLER were kept on punch cards until
1978). Running KEPLER always requires the regular KEPLER generator
specified in the next section. In addition, a separate BURN
generator, specified in the section following, is required if BURN
co-processing is specified by the inclusion of a GENBURN card in the
regular generator. Both files must be in the working directory in
which the problem is being run.
A generator card may be up to 120 characters-long and contain up to 60
blank, tab, or equal-sign delimited words, each at most 60 characters
long. Words are interpreted as being integer, character or floating
point depending on their format and must match the type specified for
each card or a fatal error message will be sent. Except as noted
below, words representing input character variables are truncated to 8
characters, while numerical input is
field-free, except that
floating point numbers must be distinguished from integers by a
decimal point or exponent.
Card types allowed in the regular KEPLER generator file are listed below.
Each card keyword is given in bold letters, followed by its arguments, if any, in ITALIC CAPITAL LETTERS. For each commands, an example is given, which also serves to indicate the expected type of the arguments. Note that, as indicated by the examples, actual communication with the computer should be made in lower case and that character parameters are never enclosed in quotes.
Complete historic sample KEPLER and BURN generator files are available, along with some useful variants. These are taken directly from recently executed KEPLER jobs.
