The example in Figure 7 illustrates the use of the ALLOCATE command
for allocating the data sets required for an execution of the Assembler
F compiler.. The assembler requires eight data sets for this
compilation. They are:
SYSLIB
SYSUTl
SYSUT2
SYSUT3
SYSPRINT
SYSPUNCH
SYSGO
SYSIN
The macro library (usually SYS1.MACLIB).
Work data set.
Work data set.
Work data set.
Output listing data set. Your terminal is allocated
for this purpose.
Data set for a punched deck of an object module. It
is to be produced on the standard message output
class. (To
ch~nge
this output class to a punch
output class, see "Freeing an Allocated Data Set".)
Data set for the object module.
Input source statements to the Assembler. It is
created with the EDIT command and defined to the
assembler with the ALLOCATE command.
