253	analyze_multics (azm) needs to support oct dec calc and index_set active functions.	Gary Dixon	Eric Swenson	"In order to define useful abbreviations for use in analyzing dumps, several Multics active functions need to be defined in the analyze_multics request environment.  These include:

- calc, plus, minus, times, divide: for calculations
- decimal, octal: for number base conversion
- index_set: for generation of a set of related numbers to permit display of a list of entries

By making these command/active-functions as azm requests, they can be used directly in azm request lines, and in abbreviations defined for use in azm requests.

These changes can easily be added to analyze_multics by listing the command/af entries in azm_request_table_.alm using the multics_request macro.  Such capabilities would permit definition of simple abbreviations to display data structures from a dump.  

Examples of such abbreviations are shown below.


{{{
azm:  sld 22
Could not find apte for process_idx 0
     dbr = 17543650
This is an early dump.

  ERF 22  in directory >dumps dumped at 09/19/21  0752.3 pdt Sun.

b cme      execute_string ""display sst$cmp,*  -as """"cma(""""[decimal &1o]"""")"""" ""
b slte     execute_string ""display slt +[octal [calc 4*[decimal &1o]+8]] -as slte""
}}}

The following shows use of the cme abbreviation to display a Core Map Entry (CME) for real memory page 337 (octal).  Note that this CME has different values in two related dump IDs: 22 and 23.
