    Format

      .INCLUDE  quoted-literal

1  –  Parameter

 quoted-literal

    The name of the source file to be included within double quotes.
    If a logical name exists that is the same as the source file
    name, specify the .M64 file extension to override the logical
    name.

2  –  Description

    .INCLUDE indicates that the current input source file should be
    suspended and that the specified file should be used. When that
    file ends, the original source stream resumes, starting at the
    line after .INCLUDE.

3  –  Notes

    o  The assembler issues an error message if the file nesting
       level exceeds 50.

        .INCLUDE "file1.m64"
