Before an z/OS UNIX
program can be run in a shell, it must be given the appropriate mode
authority for a user or group of users. You can update the mode authority
for an executable by using the chmod command. See z/OS UNIX System Services Command Reference
for the format and description of chmod. Note that
when c89 creates an executable, the file is given
execute permission for all users.
After you have updated the mode authority, enter the program name
from the shell command line. For example,
- If you want to run the program data_crunch from
your working directory,
- You have the directory where the program resides defined in your
search path, and
- You are authorized to run the program,
enter:
data_crunch
When running such programs, you can specify invocation runtime
options only by setting the environment variable _CEE_RUNOPTS before
invoking the program. For example, under a
z/OS UNIX shell you
can use the
export command. For example:
export _CEE_RUNOPTS="rpto(on)…"
To
further update the runtime options, you can issue another
export.
