On TSO, you can use TSO commands, command lists (CLISTs), REXX EXECs, or
ISPF to assemble your program. Figure 1 shows
how to allocate the data sets and assemble the source program using
the ALLOCATE and CALL commands. The commands are shown in bold text.

on TSO
You can enter ALLOCATE commands in any order; however, you must
enter all of them before you start the assembly. Table 1 shows the data sets you must
allocate when you specify particular assembler options.
