SETC_symbol
is a SETC symbol. See “SETC Instruction” on page 369.
NOSTMT
specifies that the statement to be read by the AREAD instruction is printed in
the assembly listing, but not given any statement number.
NOPRINT
specifies that the statement does not appear in the listing, and no statement
number is assigned to it.
CLOCKB
assigns an 8-character string to SETC_symbol containing the local time in
hundredths of a second since midnight.
CLOCKD
assigns an 8-character string to SETC_symbol containing the local time in the
format HHMMSSTH, where HH is a value between 00 and 23, MM and SS
each have a value between 00 and 59, and TH has a value between 00 and
99.
Assign Character String Value
The first format of AREAD functions in much the same way as symbolic
parameters, but instead of providing your input to macro processing as part of the
| macro instruction, you can supply full input records from either the AINSERT buffer
| (if any are present), or from the records in the primary input stream that follow
immediately after the macro instruction. Any number of successive statements can
be read into the macro for processing.
SETC_symbol may be subscripted. When the assembler encounters a Format-1
AREAD statement during the processing of a macro instruction, it reads the source
statement following the macro instruction and assigns an 80-character string to the
SETC symbol in the name field. In the case of nested macros, it reads the
statement following the outermost macro instruction.
If no operand is specified, the statement to be read by AREAD is printed in the
| listing and assigned a statement number. The AREAD action is indicated in the
| listing by a minus sign between the statement number and the first character of the
| record.
Repeated AREAD instruction statements read successive statements. In the
following example, the input record starting with INRECORD1 is read by the first
AREAD statement, and assigned to the SETC symbol &VAL. The input record
starting with INRECORD2 is read by the second AREAD statement, and assigned to
the SETC symbol &VAL1.
