This is related to the mode of the jsh (see also DIR does not work in jSHELL). In jsh mode it will run the jBASE version and in sh/msh modes it will run the NT version. There is an equivalent jCOPY (and jDATE) that will run the jBASE command in all jsh modes.
Note: if you PERFORM/EXECUTE a command such as COPY it will always run the jBASE version.
