If the line before the AEJECTstatement appears at the bottom of a page, the AEJECT statement has no effect. AnAEJECT instruction immediately following another AEJECT instruction causes ablank page in the listing of the macro definition.Notes:AINSERTAREAD1. The AEJECT instruction can only be used inside a macro definition.2. The AEJECT instruction itself is not printed in the listing.3. The AEJECT instruction does not affect the listing of statements generatedwhen the macro is called.instructionThe AINSERT instruction, inside macro definitions, harnesses the power of macrosto generate source statements, for instance, using variable substitution. Generatedstatements are queued in a special buffer and read after the macro generatorfinishes.The specifications for the AINSERT instruction, which can also be used in opencode, are described in “AINSERT instruction” on page 106.instructionThe AREAD instruction assigns an arbitrary character string value to a SETCsymbol.The AREAD instruction has two formats. The first format lets you assign to aSETC symbol the character string value of a statement that is placed immediatelyafter a macro instruction.254 HLASM: V1R6 Language Ref
