I'm in the USS shell under TSO, and I have this exec (named tryit ):
/* rexx */
"cd /differentdir"
"pwd"
Here's the result:
> pwd
/origdir
> tryit
/origdir
In other words, the effects of the cd command appear to last only for the duration of the command itself. Is there a way for the REXX exec to change the working directory in a way that will be recognized in following commands?
For REXX execs running under the USS shell, the default addressing environment is SH. From the Using REXX and z/OS UNIX System Services manual:
Note that built-in shell commands run in the shell process, not your REXX process and cannot alter the REXX environment. For example, address sh 'cd /' will not change the current directory of your REXX process.
To make a persistent change to the current working directory, issue the address syscall chdir
command. From the same manual:
If you use chdir to change a directory in a REXX program that is running in a TSO/E session, the directory is typically reset to your home directory when the REXX program ends.
