Example Queue 0
This queue is used to show how to calculate the string length of each
record and maximum number of records.

String Length of Record
The size of a record is limited so that the length of the maximum
formatted string does not exceed 80 characters. The following table can
be used to determine the formatted string length.
Data
delimiter
word
long word
date
time
For queue 0, the formatted string length is 59 characters, as shown below:
Data Date Time
Characters 10 1 8
= 10 + 1 + 8 + 1 + 6 + 1 + 11 + 1 + 6 + 1 + 6 + 1 + 6
= 59 characters
