xpxPrintStack

FUNCTION xpxPrintStack  (firstStackLevel     : INTEGER;
                         numberOfStackLevels : INTEGER;
                         outputFileName      : STRING;
                         options             : INTEGER) 
                         status              : INTEGER;

The xpxPrintStack function is normally used for debugging purposes. The execution stack in EDMexpressVM will be dumped (written) to the specified file and/or standard out. That is, one or both of the options XPXPRINT_LOCAL_VARIABLES and XPXPRINT_TO_STDOUT must be applied in order to obtain any output at all. Please note that the bottom element of the stack is element number 1 and the top element has the number obtained from the xpfGetStackLevels function.

Arguments

Type	Name	Comment
INTEGER	firstStackLevel
INTEGER	numberOfStackLevels
STRING	outputFileName	The full path to the output file
INTEGER	options	A bitwise OR of any of the following built in constants.
