zSecure - Allow function e.g. SUM for User-Defined Variables

zSecure gives us the ability to define our own file structures using e.g. DEVTYPE TYPE=$txt, but then doesn't allow us to use any of the fields we define in DEFINE statements, such as in SUM(xxx). It's a case of, "giving with one hand and taking away with the other". We'd like zSecure to handle this.

Example -

 1 !  deftype type=$txt                                        
2 !  define type=$txt date as word(record,01)                 
3 !  define type=$txt time as word(record,02)                 
4 !  define type=$txt type as word(record,03)                 
5 !  define type=$txt syst as word(record,04)                 
6 !  define type=$txt jobn as word(record,05)                 
7 !  define type=$txt user as word(record,06)                 
8 !  define type=$txt data as word(record,07)                 
9 !  define type=$txt ctrl as word(record,08)                 
10 !  define type=$txt bi   as word(record,09)                 
11 !  define type=$txt bo   as word(record,10)                 
12 !                                                           
13 !  alloc type=$txt dd=file                                  
14 !  option emptylist=hide required pl=0                      
15 !  suppress racf                                            
16 !  suppress ckfreeze                                        
17 !                                                           
18 !  newlist type=$txt detail title="Sum" nodup               
19 !                                                           
20 !  define type=$txt tot_in('Total bytes_in',15)   sum(bi)   
21 !  define type=$txt tot_out('Total bytes_out',15) sum(bo)   
22 !                                                           
23 !  select data=unprotected                                  
24 !                                                           
25 !  summary tot_in tot_out

    For now we will interpret this idea as adding support for a CONVERT on a DEFINE of a deftype.

    The sample CARLa has one or two wrong assumptions. It confuses character fields with binary fields. In other words, if the word with some number in the input file is in EBCDIC characters, it needs a CONVERT to DECIMAL before you perform a SUM statistic on it and expect the numbers to add sensibly. If the word in the file is already in binary form, the DEFINE must specify a format on the field definition that implies such, rather than inherit a default format from RECORD. Which of the two cases applies here?
