A MODEENT macroinstruction associates a logon mode name with a set of parameters representing session protocols.
The component description for the device represented by the logical unit should describe the features you want to use and the session protocols required to use those features. See z/OS Communications Server: SNA Programming for information about setting session parameter fields. If a bit is identified as being reserved, set it to 0.
After you have determined what bits must be set, convert the eight bits in each byte of the session parameter field into the two equivalent hexadecimal digits. The value for each operand is the hexadecimal equivalent of the bits in the byte with which the operand is associated. For example, the operand PRIPROT is associated with byte 3 of the session parameter field. If you decide, for example, that the appropriate bit settings for the byte are 1111 0001, code PRIPROT=X'F1'.
The values for the FMPROF and TSPROF operands, can be specified as unframed decimal digits (for example, 4) or as framed hexadecimal digits (for example, X'04'). The other operands require hexadecimal values.
The MODEENT macroinstruction follows the MODETAB or another MODEENT macroinstruction.
