word of the message text is split into the supplied variables from left to right.

If insufficient variables are provided, some data is not available. Excess

variables are given no value—they are set to the null string. Multiple

variables must be enclosed in parentheses and separated by commas.

beginning of this section, for more information.

SET

specifies that the message text is not to be transferred into variables. The

If SET is not specified, use other EMSREAD operands to control the way a

message is handled. The absence of any operands implies SET, which is the

default.
