Parameter Files

The parameter file is an ASCII text file where each line contains a parameter description with the following simple format:

where

• Parameter is the parameter name such as input-file.
• Type is a single character, describing whether the parameter is a text string (s), boolean expression (b), real (r) or integer (i) number.
• Query is a flag q or h to prompt the user for input of the parameter value.
  q will display the prompt text in Prompt and wait for manual input.
  h means the parameter is hidden from external input with a value given by Value.
  If after the flag there is letter l, i.e., ql or hl then the program remembers the last input and suggests it to you during next run.
• Value is the actual value of the parameter depending on its type Type.
  s expects a text string in quotes such as ``filename''.
  r expects a real decimal such as 12.345.
  i expects an integer number such as 123.
  b expects either yes or no.
  
• From is a lower limit on the parameter value in real or integer format.
• Until is an upper limit on the parameter value in real or integer format.
• Prompt is a display prompt text used to ask for manual input if Query is q and should be a text string in quotes such as ``Enter name of input observation file: ''.
