Description

The DISPLAY BREAKPOINT command displays active breakpoints when a program is being run in debug mode. Breakpoints are logical conditions. A program executing in debug mode will stop and redisplay the debug popup when the breakpoint condition evaluates to true.

DISPLAY commands differ from LIST commands in that they pause every 17 lines until a key is pressed. You can cancel any further output at this point by pressing the [ABANDON] key. Where the output is sent to a file or printer, the pause is disabled.


Keyword Description
TO <file> The display output will be sent to the specified file. The filename can be substituted with a <expC>, enclosed in round brackets, which returns a valid filename. If no file extension is specified, then ".txt" will be used. The command SET PAGELENGTH governs the output file pagination and SET PAGEWIDTH defines the width of each page. Page numbers are centered on the bottom of the page according to width.
TO PRINT The display output will be sent to a printer. The TO PRINT option will default to a local printer unless the command SET PRINTER TO \\SPOOLER is issued. The print request will then be spooled to the system printer, which is defined by the environment variable DB_PRINT.

Example

debug myapp
suspend
display breakpoint
