The file specification for a host language source file that
    contains embedded SQL statements. The default file extension
    for the source file depends on the host language specified in the
    language qualifier.

    Language Default File Extension

    Ada      .sqlada
    C        .sc
    COBOL    .sco
    FORTRAN  .sfo
    Pascal   .spa
    PL/I     .spl

    If the host language is Ada or COBOL, the file name (without the
    file extension) cannot be longer than 27 characters.

    The precompiler command line allows a list of host language
    source files in this argument, but only processes the first file
    specification it encounters. If you specify a list of files, the
    precompiler:

    o  Gives a warning message that only the first file on the line
       will be precompiled

    o  Ignores the other file specifications and passes them along to
       the host language compiler in the same order as they appeared
       on the precompiler command line

    For instance, the following command lines are valid, but only the
    MY_FILE host language file is precompiled:

    $ SQLPRE/PLI/LIS/DEB MY_FILE+MY_TLB_1/LIB+MY_TLB_2/LIB
    $ SQLPRE/PASCAL MY_FILE,MY_OTHER_FILE
    $ SQLPRE/COB/DEB MY_FILE,MY_NODB_FILE
    $ SQLPRE/CC MY_FILE+REST_OF_APPL+APPL_TLB/LIB

    For the previous command lines, the precompiler passes the
    following corresponding command lines to the host language
    compiler:

    $ PLI/LIS/DEB MY_FILE.PLI;n+MY_TLB_1/LIB+MY_TLB_2/LIB/NOG_FLOAT
    $ PAS MY_FILE.PAS;n,MY_OTHER_FILE
    $ COB/DEB MY_FILE.COB;n,MY_NODB_FILE
    $ CC MY_FILE.C;n+REST_OF_APPL+APPL_TLB/LIB/NOG_FLOAT

    The ;n notation signifies the version number of the host language
    file generated by the SQL precompiler.
