There are some parameter definitions in the CICS System Initialization Table (DFHSIT) that may cause CICS messages to be received during an Advantage CA-Ideal for CA-Datacom session. These parameters are used for CICS Basic Mapping Support (BMS=YES in DFHSIT) and are set equal to a two-byte character string. If one of these character strings is typed into an unprotected field during an Advantage CA-Ideal session, a CICS message will be received upon hitting the ENTER key. However, this string must be the first two characters of the input stream from the terminal for this to occur. These strings are not being parsed by SCF but rather by CICS. You can return to the Advantage CA-Ideal session via the CLEAR, PA1 or PA3 keys.

If any of these messages are received and the corresponding character string has NOT been entered, it is likely that the definition in the DFHSIT has been altered to a two-byte string other than the default.

If you MUST use a certain two-byte string in an unprotected field during an Advantage CA-Ideal session, then you will need to change the parameter definitions in the DFHSIT to a two-byte string less likely to be used. You should avoid using strings such as '@I' or '//' because using these strings would prohibit the use of Advantage CA-Ideal internal commands or the submission or creation of JCL, respectively.
