TI506D.txt Unknown runtime errors. What's error 163?
Category :General Programming
Platform :All
Product :Pascal All
Description:
Pascal sometimes returns runtime errors that aren't listed
in the manuals. If you ever get an IORESULT code in the range
150-199, just subtract 131 from it and the look in your DOS
reference manual (or in the list presented below) for the
relevant critical errors.
One error that users see quite often is number 163, which is
a sharing violation. It occurs when two users try to access the
same file at the same time.
Here's a list of critical errors. The first column has the
error number in decimal format, the second has the number in hex,
and the third provides an explanation of the error:
