PCA$HELP.HLB  —  SET  VCOUNTERS
    Collector Command

    Establishes the collection of vector processor instruction counts
    at specified program locations.

    Format

      SET VCOUNTERS  [nodespec [,nodepsec...]]

1  –  Parameters

 nodespec

    Specifies a set of restricted program locations that gatehr
    vector processor instruction counts within the specified range.

2  –  Description

    The SET VCOUNTERS Collector command enables the counting of
    vector processor instructions. The collected data can help you
    determine to what extent the vector processor is being used. You
    must specify at least one node specification on the command line
    to indicate the domain of the data to be collected.

    The following node specifications are used when collecting vector
    instruction counts:

    o  PROGRAM ADDRESS by VINSTRUCTION

    o  MODULE module-name by VINSTRUCTION

    o  ROUTINE routine-name by VINSTRUCTION

3  –  Qualifiers

3.1    /STACK_PCS

    Specifies that stack PC values for counter data are to be
    collected. If you use /STACK_PCS, further SET VCOUNTERS requests
    assume a default of /STACK_PCS.

3.2    /NOSTACK_PCS

    Specifies that no stack PC values for counter data are to be
    collected. This is the default setting upon entry into the
    Collector.
