RELATED IDEAS

Copy member to input stream similar to AINSERT

Provide an assembler instruction statement (ACOPY for example) to insert
a member into the input stream along the lines of AINSERT.

Customer suggested extending AREAD with a member name, but this may be
more complex than really needed, for example it implies the possibility
of reading from more than one member at a time.

    This RFE is one of a small group which had apparently been set aside incorrectly years ago and subsequently overlooked. We are sorry for the delay.

    There is an existing technique to allow a COPY file to be processed via AREAD, which is to cause the COPY file to be fetched by lookahead by using a forward attribute reference, so the AREAD will see the contents of the copy file rather than the COPY statement itself. This can all be encapsulated in a macro, using AINSERT to create an end label and issue the COPY, for example something like the following:

    MACRO
    MYCOPY &MEMBER
    &ENDLABEL SETC 'ENDCOPY_&SYSNDX'
    AINSERT ' READMEM &ENDLABEL',BACK
    AINSERT ' COPY &MEMBER',BACK
    AINSERT '&ENDLABEL DS 0X',BACK
    MEND

    MACRO
    READMEM &ENDLABEL
    &T SETC T'&ENDLABEL Cause lookahead
    .LOOP ANOP ,
    &LINE AREAD , Read next input line
    AIF ('&LINE'(1,K'&ENDLABEL+1) EQ '&ENDLABEL ').END
    ...
    AGO .LOOP
    .END ANOP ,
    MEND
    ...
    MYCOPY MEM1
