Use the
wait measurement_complete
command after changing the trace
depth. By doing this, when you copy or display the trace after changing the
trace depth, the new trace states will be available. Otherwise the new states
won’t be available.
Passing Parameters
Command files provide a convenient method for passing parameters by using
a parameter declaration line preceding the commands in the command file.
When the command file is called, the system will prompt you for current
values of the formal parameters listed.
Parameters are defined as:
Passed Parameters - These are ASCII strings passed to a command
file. Any continuous set of ASCII characters can be passed. Spaces
separate the parameters.
Formal Parameters - These are symbols preceded by an ampersand
(&), which are the variables of the command file.
The ASCII string passed (passed parameter) will be substituted for the
formal parameter when the command file is executed.
The only way to pass a parameter containing a space is to enclose the
parameter in double quotes (") or single quotes (’). Thus, to pass the
parameter HP 9000 to a command file, you can use either "HP 9000" or
’HP 9000’.
The special parameter &ArG_lEfT gets set to all the remaining parameters
specified when the command file was invoked. This lets you use variable size
parameter lists. If no parameters are left, &ArG_lEfT gets set to NULL.
Consider the command file example (named CMDFILE) shown below:
PARMS &ADDR &VALUE1
#
# modify a location or list of locations in memory
# and display the result
#
modify memory &ADDR words to &VALUE1 &ArG_lEfT
display memory &ADDR blocked words
When you execute CMDFILE, you will be prompted with:
Define command file parameter [&ADDR]
