ACIF on CMOD v10.5 may put out a new message APK511W.
See the Ricoh guide:
https://www.ibm.com/support/knowledgecenter/SSLTBW_2.4.0/com.ibm.zos.v2r4.apku000/apskumst51.htm#apk511 (https://www.ibm.com/support/knowledgecenter/SSLTBW_2.4.0/com.ibm.zos.v2r4.apku000/apskumst51.htm#apk511)
The message is issued only if the one is using the ACIF parameter CONVERT=YES and the input file is line data with consecutive stream delimiters (which are considered �blank lines�).
In order to suppress the message and get everything working again, you need to use CC=YES,DISCARD
Here are the options and behavior:
1) CONVERT=YES
cc=yes,discard no msg and RC 0
cc=yes,fix msg and RC 4 (default)
cc=yes,ignore msg and RC 0
cc=yes,strict msg and RC 16
2) CONVERT=NO
All options (discard, fix, ignore, strict) give no msg and RC 0.
This is when you're using this level of ACIF:
