When customizing BPXPRMxx, these rules apply:
- Statements that contain limiting keywords (like MAXUIDS, which
limits the number of concurrent z/OS® UNIX users), should not be duplicated
in the same BPXPRMxx member. You can have duplicates of limiting keywords
across BPXPRMxx members, but only the last occurrence is used. Resource
defining keywords (like MOUNT, which specifies a file system that z/OS UNIX is to logically mount onto
the root file system or another file system) are cumulative. Resource
defining keywords can be duplicated in the same BPXPRMxx member. Each time you specify
a resource defining keyword, its value is added to the previous values.
- If a statement that has a default is omitted, the default is used.
- Use columns 1 through 71 for data; columns 72 through 80 are ignored.
- Enter one or more statements on a line, or use several lines for
one statement.
- Use blanks as delimiters. Multiple blanks are interpreted as
a single blank. Blanks are allowed between parameters and values;
for example, MAXPROCSYS(500) and MAXPROCSYS (500) are allowed and
have the same meaning.
- Comments can appear in columns 1-71 and must begin with /* and
end with */.
- Enter values in uppercase, lowercase, or mixed case. The system
converts the input to uppercase, except for values that are enclosed
in single quotation marks, which are processed without changing the
case.
- These values require single quotation marks and are the only ones
that are allowed to be in single quotation marks:
- STEPLIBLIST
- USERIDALIASTABLE
- FILESYSTEM in the ROOT, MOUNT, and ALTROOT statements
- MOUNTPOINT in the MOUNT and ALTROOT statement
- PARM in the FILESYSTYPE, ROOT, MOUNT, SUBFILESYSTYPE, and ALTROOT
statements
- RUNOPTS
- VERSION
- AUTHPGMLIST
- Enclose values in single quotation marks, using the following
rules:
- Two single quotation marks next to each other on the same line
are considered as a single quotation mark. For example, John''s
file is considered to be John's file. One
quotation mark in column 71 and another in column 1 of the next line
are not considered as a single quotation mark. This input is treated
as two strings or an error.
- Because some values can be up to 1023 characters, a value can
require multiple lines. Place one quotation mark at the beginning
of the value, stop the value in column 72 of each line, continue the
value in column 1 of the next line, and complete the value with one
quotation mark. Figure 1 shows
an example.

Rather than defining parameter limit values in their full decimal
or hexadecimal form, you can use a one-character multiplier (denomination
values) suffix when specifying them. This value will also be used
in displays when the system returns responses to respective D OMVS
commands. The multipliers are listed in Table 1
Restrictions: - Only those SETOMVS parameters that support this C suffix
specifically note that support and refer to Table 1..
- Values that contain a multiplier are limited to 8 digits (nnnnnnnnC)
and those values are limited to X'00FF FFFF' (16 777 215
decimal).
- Values that do not contain a multiplier are limited to X'7FFF FFFF'
(2 147 483 647 decimal).
