19.6 User Scripts
In order to remain compatible with the old BPE we use the convention that BPE variables all
start with the stringV . They may be accessed in user scripts using the syntax$$bpe{V xxx}
or as menu variables in input fields of the program input files where the string $(xxx) has
to be used for accessing the BPE variable V xxx. BPE variables have precedence over menu
variables defined inMENU VAR.INP in the script’s option directory. See Section 18.5 for details
on menu variables and Section 19.6.2 for details on variables in user scripts.
Some variables have a special meaning: The special parameters V MINUS and V PLUS specify
the ranges for session variables. If defined, their values are used instead of the values of the
keywords VAR PLUS and VAR MINUS in file MENU VAR.INP of the script’s option directory. See
Section 18.5 for details on menu range variables.
The variable V CAMP may be used to define the campaign in which the BPE has to run. The
BPE will stop if it is started in another campaign. If the variable is not specified the BPE
may run in any campaign. The variable V RERUN is used to restart the user script in case of
an error. The value of this variable specifies the number of additional attempts to run the
script. This may make sense if the user script fails due to system or network problems. If
this variable is not contained in the list (or has the value 0) no reruns are performed. The
variables V D, V J, V M, V Y are reserved. Do not use them.
19.6 User Scripts
After installing the Bernese GPS Software a couple of Perl scripts can be found in directory
${U}/SCRIPT. These small programs are user scripts and complement the BPE examples
