ADD_LAST

Type: enum
Default: NO
Usage: ADD_LAST (NO|NUMERIC|SYMBOLIC)

Description: If the last iteration should be added, and if it should be marked symbolically (with lowercase letter l) or with the iteration number. Not every iteration level is able to identify the last iteration early enough to be able to output. When this keyword is activated all iteration levels are checked for the last iteration step.

Valid values:

  • NO Do not mark last iteration specifically

  • NUMERIC Mark last iteration with its iteration number

  • SYMBOLIC Mark last iteration with lowercase letter l

COMMON_ITERATION_LEVELS

Type: integer
Default: 0
Usage: COMMON_ITERATION_LEVELS

Description: How many iterations levels should be written in the same file (no extra information about the actual iteration level is written to the file)

FILENAME

Type: string
Default: __STD_OUT__
Usage: FILENAME ./filename

Description: controls part of the filename for output. use __STD_OUT__ (exactly as written here) for the screen or standard logger. use filename to obtain projectname-filename. use ./filename to get filename. A middle name (if present), iteration numbers and extension are always added to the filename. if you want to avoid it use =filename, in this case the filename is always exactly as typed. Please note that this can lead to clashes of filenames.

Type: logical

SORT_BY_SELF_TIME

Type: logical
Default: F
Lone keyword: T
Usage: SORT_BY_SELF_TIME on
