Syntax
SET-BREAK ( [ procedure [ , line-number ] ] )
|
-
procedure
- A character expression that specifies the name of the procedure
in which you want to set the breakpoint. The specified procedure
does not have to exist at the time the breakpoint is set. If you
do not specify procedure, the method sets the
breakpoint at the next executable line of the current procedure.
-
line-number
- An integer expression that specifies the line number in procedure (based
at line 1 of the debug listing) where you want to set the breakpoint.
A positive integer greater than or equal to 1 represents a line
number in the specified procedure file. Zero
(0) or a negative integer value represents the first executable
line of the main procedure block in the specified procedure file.
If you do not specify line-number, the method
sets the breakpoint at the first executable line of procedure file.
If line-number is greater than the last executable
line number, the method sets the breakpoint at the last executable
line of procedure. If line-number does
not specify an executable line, the method sets the breakpoint at
the next executable line after the line specified by line-number.
If
the Debugger is initialized, this method returns TRUE. Otherwise,
it returns FALSE with no effect. For more information, see the reference
entry for the DEBUGGER system handle.
Note: To use this method, you must
have the Application Debugger installed in your OpenEdge environment.
Note that the Debugger sets breakpoints on physical lines—not statements. If you
invoke DEBUGGER:SET-BREAK( ) on a line that contains other executable
statements, all the other statements on that line execute before the breakpoint occurs on
the next executable line. This is true whether the statements appear on the same line before
or after the invocation of the SET-BREAK( ) method.
If you invoke DEBUGGER:SET-BREAK ( procedure ,
line-number ) on the same line that is specified by
procedure and line-number, the specified line
executes the first time without breaking. The breakpoint occurs only on the second and
succeeding executions of the line.
Note: You cannot set a watchpoint programmatically
using the DEBUGGER system handle. A watchpoint is a form of breakpoint
which tells the Debugger to interrupt program execution when the
value of a variable, buffer field, or attribute reference changes.
