The COMPILERTARGET (Set Default Target Value) command sets the default value for the compiler option TARGET.
Syntax
Explanation
Many of the language compilers can produce code files that run only on a particular set of computer families. For more information, refer to the description of the TARGET compiler option in the appropriate language reference manual.
The COMPILERTARGET command changes the default value of TARGET. The new value remains in effect until it is changed by another COMPILERTARGET command. The value specified in the COMPILERTARGET command is preserved across all halt/loads, but not across cold-starts. After a cold-start, the value is reset to the default value supplied by the manufacturer. The primary and secondary target values are specified as an operator set (LEVEL6, ALL) or as a machine name (for example, GE1500).
Supported Target Values provides the supported primary and secondary target values.

Most compilers generate code files that are optimized for the systems represented by the primary target, subject to the compatibility constraints of the systems represented by the secondary targets. For example, the compiler optimizes the code for the primary target but does not generate an operator unless it is supported by all of the secondary targets.
The target value THIS is equivalent to specifying the current machine name. If the target value specifies a machine name, it is mapped to the machine’s primary operator set.
Some machines support extensions to the LEVEL6 operator set which can improve code file performance. To enable these extensions by default, set COMPILERTARGET = THIS. Use caution with this feature since the compiled code may not be executable on all LEVEL6 machines. Check the COMPILERTARGET response to see how the setting affects code file compatibility.
ALL and LEVEL6 are currently synonyms. If these values are specified, the generated code file can run on all supported machines.
LEVEL6 code files are optimized for level Eta systems. See Supported Target Values for a list of currently supported level Eta system target values.
COMPILERTARGET
Displays the current default value of the TARGET compiler option.
COMPILERTARGET = <primary target>
Assigns the specified target value as the default value for the TARGET compiler option.
COMPILERTARGET = <primary target> (<secondary target>)
Assigns the specified primary target value as the default value and also assigns the secondary target value.

The following lists a sample response to the command COMPILERTARGET LEVEL6:
