Examples

The output above illustrates that parameter Param^1 is stored in register $4 or $A0

and that parameter Param^2 is stored in register $5 or $A1 and is indirect. The

Inspect DISPLAY and DISPLAY REGISTER commands can be used to display the

contents of these variables.

4. Using a Signal Handler to Control Program Flow

Inspect allows you to change a signal handler to several values, including

SIG_DEBUG which can be used to gain control of a program when a signal is

delivered. For example, if a TNS/R native application is receiving an arithmetic

overflow trap (signal SIGFPE), change the signal handler for SIGFPE and rerun

the program. For example:

-PROG-INFO IDENTIFIER Param^1

PARAM^1: VARIABLE

storage^info:

TYPE=BIN SIGN, ELEMENT LEN=16 BITS, UNIT SIZE=1

ELEMENTS

access^info:

-PROG-INFO IDENTIFIER Param^2

PARAM^2: VARIABLE

storage^info:

TYPE=BIN SIGN, ELEMENT LEN=16 BITS, UNIT SIZE=1

ELEMENTS access^info:

-PROG-DISPLAY Param^1

PARAM^1 = 10

-PROG-DISPLAY REGISTER $4

-PROG-DISPLAY Param^2

PARAM^2 = 99

-PROG-DISPLAY REGISTER $5

-PROG-DISPLAY (1342177068) TYPE INT
