DISPlay Map - display profile of executed instructions.

Syntax:

disp map [nn]    (where nn is the nn(octal)
                  most active frequencies)

Examples:

disp map
disp map 5

Description:

If a map trace has been engaged, this selection will display the resulting map showing consecutive subdivisions of the tracing region interval and the number of instructions executed in each such subdivision. Columns of this report will be identified by a heading title, as follows:

LOC. INTERVAL    ID FREQUENCY      %   CUM %

or, if the subdivision is unity,

LOC.     ID  FREQUENCY       %   CUM %

LOC. INTERVAL represents the range of the subdivision and will consist of an address interval, A1-A2, inclusive. The first line of the report will have an "A" or "R" appended to the interval specification indicating whether the addresses are absolute or relative, respectively. The meaning of other column identifiers is as follows:

ID: This column contains the mnemonic operation code of the instruction word at location A1; i.e., the first location of the subdivision. If the op code is illegal, the field will be left blank.
FREQUENCY: This column contains a decimal count indicating the total number of instructions which have been executed in the subdivision. Subdivision intervals which have had no activity (i.e., the frequency is zero) will not be shown in the report.
%: This column contains a decimal quantity indicating what percent the subdivision's frequency is of the total number of instructions executed by the target program.
CUM %: This column indicates cumulative percentage. It simply consists of a running total of the % column.

Both percentages mentioned above will be rounded to the nearest hundredth of a percent; e.g., 23.084 would be truncated to 23.08, while 23.085 would be rounded up to 23.09. Percentages will not be shown for subdivisions having a frequency which represents less than .005% of the total number of instructions executed by the target program.

If desired, a partial map may be displayed, showing only subdivisions with the highest frequencies. This optional form of the display is requested by accompanying the map selection with an OCTAL value (N), indicating how many subdivisions are to be shown. The resulting map will thus consist of the N most active subdivisions sorted in descending order according to frequencies.
