hello_world's Introduction

This is a simple hello world program for testing git on z/OS. It's meant to be used in conjunction with Using git for z/OS with GitHub on the Rocket Community Forum.

Here's a suggested scenario demonstrating how git can work with MVS datasets:

Clone this repository. If you want to push changes, fork it instead and then clone the fork.
cd into the repo and type make. This will compile and link the code and test the resulting executable.
Run ./allocate.sh. This will create three PDSes (named DEMO.{H,C,TXT}) on MVS that will contain members corresponding to the source files in the Unix file system.
Run ./to_pds.sh to populate the PDSes. This would be run any time the git repo is refreshed (via git pull).
Log into TSO, edit one of the source files, and save it.
Back at the Unix command line, run ./from_pds.sh to copy the files back from MVS to Unix. This will also run a git status command, showing the changes.
When all done, run ./cleanup.sh to delete the MVS datasets.

Also present are batch job equivalents of the to_/from_pds.sh scripts.

git-sh-setup: line 342

When i issue git push or git pull commands, i get

git pull origin mybranch /usr/local/libexec/git-core/git-sh-setup: line 342: cd: ÅÑÈ: EDC5129I No such file or directory.
line 342 in the script shows:
BROWSE /Z22R01/usr/local/libexec/git-core/git-s Line 0000000342 Col
.test -n "$GIT_DIR" && GIT_DIR=$(cd "$GIT_DIR" && pwd) || {
..echo >&2 "Unable to determine absolute path of git directory"

is there any issue with $GIT_DIR ?

file allocate_sh should be changed for the allocation of demo.txt, and assign an lrecl > 259 (for instance 286), otherwise script to_pds.sh will get an error
SPARKID:/u/sparkid/hello_world/hello_world: >./to_pds.sh
