One more thing.

You write:

memcpy (sfrcd.S01FUNC , " ", 2 );

memcpy (sfrcd.S01APFILE, " ", 10 );

memcpy (sfrcd.S01APLIB , " ", 10 );

memcpy (sfrcd.S01APACCP, " ", 1 );

memcpy (sfrcd.S01APUNIQ, " ", 1 );

memcpy (sfrcd.S01APSELO, " ", 1 );

memcpy (sfrcd.S01APFTYP, " ", 1 );

memcpy (sfrcd.S01APJOIN, " ", 1 );

memcpy (sfrcd.S01APKEYO, " ", 1 );

memcpy (sfrcd.S01APKSEQ, pfrcd.APKSEQ, 1 );

memcpy (sfrcd.S01APKSIN, pfrcd.APKSIN, 1 );

memcpy (sfrcd.S01APKEYF, pfrcd.APKEYF, 10 );

My advise is to do it another way:

memset (&sfrcd, ' ', sizeof(sfrcd)) ;

memcpy (sfrcd.S01APKSEQ, pfrcd.APKSEQ, 1 );

memcpy (sfrcd.S01APKSIN, pfrcd.APKSIN, 1 );

memcpy (sfrcd.S01APKEYF, pfrcd.APKEYF, 10 );

C differs from other languages - it does not initialize variables

on declarations in general, and structures - in particular.

So by setting full structure to spaces and then assigning/initializing

only specific fields you make your program at least shorter. But also more

Of course you must take care of numeric fields -
you have to explicitly assign valid numeric values to them before
