Use this command to initiate trace recording in the wrap around
core block mode for the specified symbolic line numbers.
Requirements and Restrictions
None.
Format
- PRC
- specifies symbolic line number (SLN) 01 is to be traced. This also
turns on the console trace bit for this subchannel.
- RO
- specifies SLN 00 is to be traced. This also turns on the console
trace bit for this subchannel.
- linetype
- is the type of line to be traced (BS/AI/LC).
- ALL
- indicates all valid SLNs for the specified line type are to be
traced.
- linenum
- is the specific line numbers to be traced; a maximum of 8 line
numbers is allowed.
- line1
- specifies the first line number in the range to be traced.
- line2
- specifies the second line number in the range to be traced.
Additional Information
- A ZLTRL command received after a ZLTRN command will suspend recording on
the RTL/RTA tape, but will continue tracing the previously specified lines in
the wrap around core block mode.
- A ZLTRN command received after a ZLTRL command will allow tracing on the
previously specified lines to continue, but will cause all trace information
to be written to the RTL/RTA tape.
- The PRC/RO options are only valid when the PRC and RO are on symbolic
lines 00 or 01. Where more than one ZLTRN command is given, their
effect is cumulative.
Examples
