Subscript ranges

Ranges appear in JES2 initialization statements and commands as subscripts of the name associated with the initialization statement.

REDIRect(vvvvvvvv)

$ADD REDIRect(vvvvvvvv)

Note: The name of the initialization statement and the target of the command are the same.

All KEYWORD= ranges must be coded explicitly; whereas subscript ranges can either be coded explicitly or as a generic range using the asterisk (*). The use of parenthesis with a generic range is optional for all numeric ranges, but is required for symbolic (character) ranges. Throughout this information the parentheses are included for consistency and clarity of presentation. It is recommended that you use parentheses when you specify a range.

Example: Initialization statement (generic subscript)
```
NODE(5-*) PATHMGR=NO
```

Example: Commands (generic subscript)

$d jobclass(d-*),qheld=yes,qheld

$Doff(*-5).JT,CLASS=a,b,c,z

$D OFF(1-10).ST

How JES2 interprets the use of the asterisk in specifying the subscript depends on how it is used in the command or statement. Table 1 shows how the asterisk is coded to indicate various ranges.

Table 1. Coding asterisks on initialization statements
`RANGE INTERPRETATION and RESULT`
`* All values in the range (for nodes and jobclasses) Statement: NODE() COMPACT=1,.-->All nodes Command: $d jobclass(),. -->All jobclasses`
`n-* Range from n to highest value Statement: NODE(5-) compact=2 -->5 to highest value Command: $Dnode(3-)NAME=XRAY -->3 to highest value`
`-m Range from highest descending to m Statement: PRT(-1) ws=(W,Q,R/) -->highest to 1 Command: $d jobclass(*-C),qheld=yes -->highest to C`
`c* All values starting with char "c" Statement: APPL(OUT).JT All APPLs starting with OUT Command: $d jobclass(A),... -->All jobclasses starting with A`
Note: When specified in a numeric range, the asterisk always indicates the highest defined value in either the ascending (n-) or descending (-m) order.
