This could be a simple issue easy to be resolved but I'm just starting testing it on mainframe,  I'm not able to collect the result from a command and save it to a file , it gives me the known error  "UnboundLocalError: local variable 'local_content' referenced before assignment" - but the I've tried to define it in a different variable, (setfact) tried loading it from hostvars, using block, etc. the "reference before assignment" doesn´t make much sense as i've tested it and confirmed it can be loaded inside that play.  Would you know the best way to save any command's result to a file / dataset.

Hello Fernando Alfredo Custodio, 

I have not tried your scenario yet, but wondering if you tried any of these things that might help narrow down where the issue is:

- Use a hard coded value instead of the fact
- Use the var resultado.content instead of the fact
- Use vars: and define your a var at the top 

Below is an example snippet of one of mine but I defined the vars for it like so:

---
- hosts: zvm
  collections:
    - ibm.ibm_zos_core
  gather_facts: false
  vars:
    PDSE: "ANSIBLE.COBOL.LOADLIB"
    PDS: "IMSTESTL.TNUC0"
    MEM_PGM: "HELLOPGM"
    MEM_TEST: "HELLODDD"
    USS_EXE: "/tmp/HIPGMUSS"
    VOLUME_PDSE: "SCR03"
    VOLUME_PDS: "USER01"
    USS_DZIP: "/tmp/temp_backup.dzp"
    USS_BINDER_JCL: "/tmp/binder.jcl"
    USS_SUB_EXE: "/tmp/pgmexe.jcl"

  environment: "{{ environment_vars }}"

  tasks:
    - name: Generate "{{ USS_SUB_EXE }}" on USS to execute library
      zos_copy:
        content: |
          //{{ MEM_TEST }}  JOB MSGCLASS=H,MSGLEVEL=(1,1),NOTIFY=&SYSUID,REGION=0M
          //STEP1    EXEC PGM={{ MEM_TEST }}
          //STEPLIB DD DSN={{ PDSE }},DISP=SHR
          //SYSPRINT DD SYSOUT=*
          //SYSOUT   DD SYSOUT=*
          //
        dest: "{{ USS_SUB_EXE }}"
        force: yes
      register: result
      tags: ocopy

Looking at your error though, i don't think you should have seen a traceback , likely something got by the exceptions, but it does look like the fact is not available yet and not sure why without testing. Some specualtion is that the operator is executing on the managed node and zos_copy being made of two parts, a plugin and module, the plugin here is throwing the error, maybe the fact has not been made avaialbe to the plugin running on the controller. 

Source in question:

 if content:
                try:
                    local_content = _write_content_to_temp_file(content)
                    transfer_res = self._copy_to_remote(
                        local_content, ignore_stderr=ignore_sftp_stderr
                    )
                finally:
                    os.remove(local_content)
