For more information about compilers, see the C/C++ Programmer’s Guide, the
COBOL Manual for TNS and TNS/R Programs, and the pTAL Reference Manual.
TNS/R Breakpoints
When debugging Accelerated programs, you can list and clear TNS/R breakpoints, but
not set them. You must set TNS/R breakpoints from Debug. There are specific rules
that apply to setting TNS/R breakpoints; for more information, see the Debug Manual.
If you set a TNS/R breakpoint and the program transfers to execute TNS code (as
opposed to TNS/R instructions) at that point in the program, the TNS/R breakpoint will
not be triggered.
When debugging TNS/R native programs, you can set breakpoints at any location in
the program. To set a breakpoint in native code, you can either specify a scope name
or a machine-level code address.
Example
This example shows using Debug to set a TNS/R breakpoint and clearing TNS/R
breakpoints using the CLEAR command with the appropriate breakpoint ordinal:
TNS/R Machine Registers
Within Inspect, you can display the value of these TNS/R machine registers when
debugging TNS/R programs:
