The records read by the AREAD instruction can be in code brought in with the
COPY instruction, if the macro instruction appears in such code. If no more
records exist in the code brought in by the COPY instruction, subsequent
statements are read from the AINSERT buffer or the primary input stream.
Assign Local Time of Day
The second format of AREAD functions in much the same way as a SETC
instruction, but instead of supplying the value you want assigned to the SETC
symbol as a character string in the operand of the AREAD instruction, the value is
provided by the operating system in the form of an 8-character string containing the
local time. A Format-2 AREAD instruction does not cause the assembler to read
the statement following the macro instruction.
Example:
MACRO
MAC2
.
&VAL AREAD CLOCKB
DC C'&VAL'
&VAL1 AREAD CLOCKD
DC C'&VAL1'
.
MEND
When the macro definition described above is called, the following statements are
generated:
MAC2
+ DC C'32514'
+ DC C'9154'
ASPACE Instruction
Use the ASPACE instruction to insert one or more blank lines in the listing of a
macro definition in your source module. This separates sections of macro definition
code on the listing page.
