Role
Implementation
This function is used to display, on the screen of a CCX 17 console, a message with a variable which can be modified by the operator.
The entry is made in synchronized mode. Therefore, it is possible to make one single operator entry at each message display.
Implementation of the ASK_MSG function is developed in the Description of parameters (See Description of the parameters common to the different DOP
functions, p. 276) section.
Note: It is strongly advisable to assign parameters for the timeout for an infinite period (see
Parameters field: Report, p. 283 so as not to invalidate the ASK_MSG
function before the operator entry is made.
Specific parameter: Value
The Value parameter specifies the characteristics of the value which is associated to the variable.
