Using SoftBench Debugger
Examining and Changing Data in Your Program
Chapter 7 183
For example, if you declare a pointer as int *numptr, then selecting
Print* ( ) with numptr in the "()" input box prints the integer pointed to by
numptr. You can also Print ( ) the expression *numptr.
Printing Hex or String Values
SoftBench Debugger knows the type of the variables you print, and
usually prints them in a usable form. However, it cannot tell if an integer
should be printed in decimal or hexadecimal, nor can it tell if you want a
"char *" value to be printed as a character or a string.
You can specify the print format by choosing one of the selections under
"Show: Data Value → Print Format ". Refer to online help for
information on printing strings and character arrays.
If you frequently need to print hex or string values, you can define a
button to do it on the front panel. See “Customizing User Buttons” on
page 228.
You can also use C-style "casting" to view variables in a different format.
If you wanted to examine the bottom byte of mask as a character, you
could enter "(char) mask" in the "()" input box and select Print ( ).
Changing Data in Your Program
1. Type an assignment statement in the "()" input box.
2. Select Print ( ).
For example, the assignment "n = 12" sets the value of n to 12. The
assignment statement must be legal in the current scope. That is, n must
be a declared numeric data type.
You can also call functions that modify their arguments.
For more information on the syntax of variables and expressions, see
“Using Debugger Variables” on page 183 or “Specifying Variables” on
page 178.
Using Debugger Variables
DDE supports user-created special variables for use as global
temporaries during debugging. For example, to create a pointer to an
integer, enter
declare int *tptr
