These commands are valid only when you call them within the PDF component. Exceptions are the primary and line commands for Edit (option 2), which are defined in z/OS V2R2 ISPF Edit and Edit Macros, and those for SCLM (option 10), which are defined in z/OS V2R2 ISPF Software Configuration and Library Manager Guide and Reference. The ISPF primary option that you are using determines which commands are valid. For example, the CAPS primary command is valid only when using the Edit option.
For information about which commands are valid for a particular option, see the relevant topic in the z/OS V2R2 ISPF User's Guide Vol II that describes the option.
PDF component primary commands can affect a complete data set or PDS member, but the line commands can affect only one or more specified lines within a data set (unless you specify all the lines in the data set). For example, the Edit COPY command can copy a complete data set, whereas the C or CC Edit line command can copy only lines or blocks of lines within a data set.
