A: Basically this is a case of RTFM (read the f*ing manual). But it
is very easy to find out even without resorting to the manual. Put
temporarily the statement RunError (205); as the first statement of
your program. Then run your program from the Turbo Pascal IDE, that
is from within the TP editor. The description of the error will
appear.
   If you run a program from within a Turbo Pascal IDE, it is
advisable to turn on the debug options on. You'll get both the error
number and the description. Furthermore by pressing F1 after the
error you get its description in a more verbal format.
   One further trick is to put "uses TSERR"; (Include verbal
run-time error messages) into your program. If you do that, the
run-time errors will be given with a verbal description not just as
a number. TSERR.TPU is part of my TPU collection at Garbo
ftp://garbo.uwasa.fi/pc/ts/tspa3470.zip.
   In TP 7.0 the run time errors can also be found by invoking
"Help" from the main manu (Alt-H) and selecting "Error messages".
