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.
