Issue/Introduction

The following doesn't work on RHEL9, while on RHEL8 and RHEL7, this works fine:

[<user>@<server> bin]$ ./ucxblx6c INI=./ucxbxxxc.ini <<EOF
> :set &HND#=ACTIVATE_UC_OBJECT(SCRI.CALLAPI)
> EOF
usage: ucxbxxxc script=<file> [logon=<client>,<user>,[<dept>],[<pass>]] [ini=<file>] [queue=<name>]
 script= ... includes the UC4 Operations Manager script
 logon=  ... UC4 Operations Manager logon information
 ini=  ... Use this INI file
 queue= ... UC4 queue name, use this 'queue' for start script
[<user>@<server> bin]$

The same happens when the above is added to a script:

#!/bin/ksh

./ucxblx6c INI=./ucxbxxxc.ini <<EOF
:set &HND#=ACTIVATE_UC_OBJECT(SCRI.CALLAPI)
EOF

Execution of the script:

[<user>@<server> bin]$ ./script.ksh
./script.ksh
usage: ucxbxxxc script=<file> [logon=<client>,<user>,[<dept>],[<pass>]] [ini=<file>] [queue=<name>]
 script= ... includes the UC4 Operations Manager script
 logon=  ... UC4 Operations Manager logon information
 ini=   ... Use this INI file
 queue=  ... UC4 queue name, use this 'queue' for start script
[<user>@<server> bin]$

The more common way of execution with INI= and SCRIPT= works well:

[<user>@<server> bin]$ ./ucxblx6c INI=./ucxbxxxc.ini SCRIPT=./script.txt
