Read(variable[,filename][,maxdigits][,option][,attempts][,timeout])

Reads a #-terminated string of digits a certain number of times from the user into the given variable.

Other arguments include:

filename

Specifies the file to play before reading digits.

maxdigits

Sets the maximum acceptable number of digits. If this argument is specified, the application stops reading after maxdigits have been entered (without requiring the user to press the # key). Defaults to 0- (no limit, wait for the user to press the # key). Any value below 0 means the same. The maximum accepted value is 255.

option

Specify skip to return immediately if the line is not answered, or noanswer to read digits even if the line is not answered.

attempts

If greater than 1, that many attempts will be made in the event that no data is entered.

timeout

If greater than 0, that value will override the default timeout.

Returns -1 on hangup or error and 0 otherwise.
