OSS Pathnames

An OSS pathname in the OSS attributes PROGRAM, STDIN, STDERR, and STDOUT

can be an absolute pathname or a relative pathname. Case is significant.

When specifying an OSS pathname longer than one line, use the PATHCOM

continuation character (&) at the end of the line to indicate continuous input. If the

pathname includes an ampersand (&) as part of the name and the ampersand occurs

at the end of an input line, enter two ampersands. An ampersand occurring in the

middle of an input line, embedded in a pathname, need not be doubled. To embed

blanks, quotes, commas, and semicolons, use the same rules as for PATHCOM; in

other words, enclose the entire pathname in quotes.

Absolute Pathnames

Absolute pathnames must begin with a forward slash (/) and can have a maximum

length of 1023 characters; the last character (character 1024) is reserved for a null.

When setting an OSS pathname using the SET SERVER CWD command or when

setting a default directory using the CMDCWD command, you must specify an

absolute pathname.

Absolute pathnames specified for server process attributes are validated when the

SET SERVER command is processed.

Relative Pathnames

At process time, PATHCOM treats any OSS pathname that does not begin with a

forward slash (/) as a relative pathname and expands it to create an absolute

pathname.

When expanding a relative pathname, PATHCOM adds a forward slash and attaches

the OSS directory specified in the SET SERVER CWD command. If no directory has

been set, the default set with the CMDCWD command is used. If the value of the

CWD attribute ends with a forward slash, then PATHCOM does not add another one.

Relative pathnames specified for server process attributes are initially validated when

the SET SERVER command is processed; additional validation is performed during the

execution of the ADD SERVER and ALTER SERVER commands. An error message is

generated at the time an ADD SERVER or ALTER SERVER command is processed if

either of these conditions apply:

•

The expansion of a relative pathname results in an absolute pathname greater

than the maximum 1023 characters allowed.
