Symbol
Initiates data tracing. Used in conjunction
with flags in the AR area to simplify
debugging. Parameters are set using the
Address Trace operation on a
Programming Console or other System
Support Tool (e.g., FIT, GPC, or LSS). AR
1815 starts sampling, AR 1814 starts the
TRSM(45)
recording of the samples which are
written to the Trace Memory of the GPC,
FIT, or LSS. A positive or negative delay
can be set for the recording of the
samples. AR 1813 and 1812 indicate
tracing in progress and tracing complete,
respectively.
Displays eight words of ASCII code,
starting from FM, on the Programming
Console or GPC. All eight words must be in
the same data area.
