Launching sp_ctrl results in "warning: parenthesize argument(s) for future version and syntax error, unexpected tINTEGER, expecting $end" (4301551)

The following messages are observed when attempting to invoke sp_ctrl despite it being launched using the correct environment settings:

$ ./sp_ctrl

./sp_ctrl:192: warning: parenthesize argument(s) for future version

./sp_ctrl:192: warning: parenthesize argument(s) for future version

./sp_ctrl:192: warning: parenthesize argument(s) for future version

./sp_ctrl:192: syntax error, unexpected tINTEGER, expecting $end

However, it is possible to connect to sp_ctrl remotely from the corresponding source/target using the option “on host” and then issue any sp_ctrl command.  For example, if the problem happens on the target server named SysB, and if the source server is named SysA, one can still launch sp_ctrl on target via sp_ctrl on source SysA as:

sp_ctrl(SysA)>qstatus on SysB

Of course one would be prompted to furnish the username and password for the spadmin user on SysB to be able to get the output of the command.
