Further information
1. This function creates a formatted string from a string or an integer or real number. It can be used at any place where strings may be used. Its most likely use is for generating printed output (in combination with
write and
writeln).
2. If the resulting string is longer than the reserved space it is not cut but printed in its entirety, overflowing the reserved space to the right.
