In shell commands (for example when using scpg3), MVS data set names must be placed in regular quotation marks (" "). This is to prevent the single quotes and parentheses in the data set names from being interpreted by the shell. Alternatively, you can use backslashes (\) to escape the single quotes and parentheses, for example //\'USER1.DATASET.NAME1\' or //DATASET.NAME1\(MEMBER1\).
