For each service, the command procedure or command invocation format is shown, followed by the call or call invocation format.
The command formats are provided as CLIST or REXX command procedures, using ISPEXEC.
Call formats are shown in PL/I syntax, although you are not limited to PL/I calls. For example, ";" ends statements in the formats described. This is a PL/I convention, but you should use the syntax appropriate for your programming language.
Consider using the Edit model facilities when you code requests for ISPF services. This will save keying the parts of dialog elements that are constant regardless of the function in which they are used. See z/OS V2R2 ISPF Edit and Edit Macros for a description of these facilities.
