PBER  4DOS  Batch  Command

PBER batch command compiles a procedure (external program executable from the command prompt), and reports the line number within the source text that corresponds to the run-time error address received during program's failed execution.  It "knows" and uses two hardcoded important locations:

%DOS%:\PWRBASIC\PBC   PowerBASIC command-line compiler program EXE module.
%DOS%:\PBASIC Directory with PowerBASIC source procedure.

PBER batch command provides a simplified interface to PowerBASIC post-debugging diagnostic facility of determinig the line number of program statement that caused execution error by the run-time error address.

Demo of PBER command operation can be found below the command text.
