Sample TSSINST1 Mode Table Format Is Incorrect

Issue/Introduction
When using a Top Secret exit based on the sample member TSSINST1 in the CAKOSRC0 library, the sample TSSINST1 implies that TXACMODE points to a mode table, the first word of which is a count of the number of modes. However, when abending the exit in the COMMAND entry point, the first word is not a count.
When the security administrator issues a TSS PER(acid) MODE(WARN), the command fails with:
TSS0226E REQUEST FAILED BY INSTALLATION EXIT
TSS0301I PERMIT FUNCTION FAILED, RETURN CODE = 4
Environment
Release : 16.0
Component : CA Top Secret for z/OS
Resolution
The sample code given in the TSSINST1 member is not correct.
If the following command is issued:
TSS PERM(acid) MODE(FAIL,IMPLE,DORMANT)
then the actual mode resource table will be returned as follows:
+0 (2) 00C3 <- this is the rescode for MODE and will always be the same
+4 (2) 0003 <- this contains the number of modes issued on the TSS command
+7 (1) 03 <- this is the length of the first mode in the table
+8 (255) FAIL <- first mode
+107(1) 04 <- length of second mode
+108(255) IMPLE <- second mode
+207(1) 06 <- length of third mode
+208(255) DORMANT<- third mode
TXACMODE = A(MODE TABLE)
