tbreak

The tbreak command sets a temporary breakpoint.

Syntax

tbreak [ { function | [ module: ] line } ] [ if condition ]

function is a function name.
module is a specific source file.
line is a source code line.
condition is an expression evaluated dynamically.

Usage

The tbreak command sets a breakpoint for one stop only.

The breakpoint is set in the same way as with the break command, but the breakpoint is automatically deleted after the first time your program stops there.

If a condition is specified, the program stops at the breakpoint only if the condition evaluates to true.

If you do not specify any location (function or line number), the breakpoint is created for the current line. For example, if you write "tbreak if var = 1", the debugger adds a conditional breakpoint for the current line, and the program will only stop if the variable is equal to 1 when reaching the current line again.

Example

(fgldb) tbreak 12 
Breakpoint 2 at 0x00000000: file custmain.4gl, line 12.
(fgldb)
