Definition of Symbols

The definition of the symbols takes place via an ordinary text file, created and maintained in the standard editor of the computer system.

The name of the file can be selected quite freely and its total name (path+name) should be assigned to the environment variable SBH_PENETR_SYMB_CTRL.

The file is divided into a number of statements. Each statement must be written in a separate line and the maximum line width is 80 characters. Spaces between terms are ignored but no blank lines are allowed.

Note: Each statement must be terminated by a semicolon (;).

The layout of all lines is identical:

The designation does not have to be complete, for example, HOL,HE,55; designates symbol 55 to all elliptical holes, that means, there is a kind of implicit "wild card" facility.

Additionally there is an option to define a default symbol for all notches or holes not otherwise defined. This is done by giving an empty designation. Holes and notches must have separate default specifications. If multiple default statements of the same kind exist, only the last one is used.
