The following additional assembler instructions are provided with High Level Assembler:

*PROCESS statement:

The *PROCESS statement lets you specify assembler options in the assembler source program. See Specifying assembler options in the source program.

ACONTROL instruction:

The ACONTROL instruction lets you change many assembler options within a program.

ADATA instruction:

The ADATA instruction allows user records to be written to the associated data file.

ALIAS instruction:

The ALIAS instruction lets you replace an external symbol name with a string of up to 64 bytes.

CEJECT instruction:

The CEJECT instruction allows page ejects to be done conditionally, under operand control.

CATTR instruction (z/OS and CMS):

You can use the CATTR instruction to establish a program object external class name, and assign binder attributes for the class. This instruction is only valid when you specify the GOFF assembler option to produce generalized object format modules. See Generalized object format modules (z/OS and CMS). By establishing the deferred load attribute, text is not loaded when the program is brought into storage, but is partially loaded, for fast access when it is requested.

EXITCTL instruction:

The EXITCTL instruction allows data to be passed from the assembler source to any of the input/output user exits. See Using exits to complement file processing.

RSECT instruction:

The RSECT instruction defines a read-only control section. See Read-only control sections.

XATTR instruction (z/OS and CMS):

The XATTR instruction enables attributes to be assigned to an external symbol. The instruction is only valid when you specify the GOFF assembler option to produce generalized object format modules. See Generalized object format modules (z/OS and CMS). The linkage conventions for the symbol are established using this instruction.
