11.2.6.5. Call Stack view
The Call Stack View displays symbol and function-call information for the process that is currently
selected in the Process View. If the Process View has no selection, this view will be empty.
The upper part of the Call Stack View displays a list of function calls made by the selected process. The
top one is the line that the process is currently executing. All other items point to the script line at which a
function call was made to the function the item above it is currenlty executing. In the example above,
currently the function "mul32U" is being executed. This function was called by "testMul32U", which on its
turn was called by "doAllTests", which on its turn was called by "testMath". The last one is an entry
function and therefore the root of the call stack.
The lower part of the Call Stak View displays a list of local and global variables that were available to the
script at the script line corresponding to the selected function call. The values of these variables are
displayed in both their native format and in raw HEX format. The last column displays the data type of the
variable. In the example above, the function call is selected that was made at script line 268. At this line,
the variabled "a, b, result and reference" were available and their values can be seen in the picture above.
If the Process View is used to "step into" or "step" through the script, the symbol list will indicate changes
by displaying them in red.
11.2.6.6. Error View
Many of the Scriptor library functions will return a negative value in case of error. When running in debug
mode, these negative return codes will always be sent to the debugger, even if the script does not contain
any return value checking.
