10.20.2 PTraceVar( ) : Parser Trace Variable
Format
PTraceVar( var1, var2 , …> )
Parser Trace Variable outputs the values of the supplied comma-separated variables. Numeric
variables are output in decimal and hex format. Packet variables are output in byte streams (hex).
This primitive does not accept constants or data patterns, which generate parse errors.
Note: Numeric variables are DWORDS.
Example
51:
packet GenericData
52: {
53: DATA : *
54: }
55: GenericData $XYZ { DATA = {
00 11 00 11 00 11 00 11 } }
56: global_var = 7
57: Main
58: {
59: local_var =
12
60: PTraceVar ( global_var, local_var, $XYZ )
61:
Send $XYZ #Send $XYZ with the following data for the instance.
62: {
63: Data = {
AA BB CC DD }
64: }
65: PTraceVar ( $XYZ )
66:
# Modify the value of $XYZ.
67: $XYZ { DATA = { EE FF 00 11 global_var local_var } }
68: local_var = 777777
69: PTraceVar ( $XYZ, local_var )
70:
Send $XYZ # Send $XYZ.
71: PTraceVar ( $XYZ )
72: }
