Write(), WriteLn() and WriteStr() (and Str()) allow to adjust the way a 
numerical value is written by using additional parameters delimited by 
colons: VarToOutput:NumChars[:Decimals] (see 
https://www.freepascal.org/docs-html/current/rtl/system/write.html ). 
That it nevertheless compiles correctly and executes as "Writeln(F, 
'Hello')" is due to a bug in the handling of the parameters. So, please 
report a bug with a complete example that should fail.
