(*====================================================================*\
|| MODULE NAME: ErrMsg ||
|| DEPENDENCIES: System ||
|| LAST MOD ON: 9004.08 ||
|| PROGRAMMER: Naoto Kimura ||
|| ||
|| This unit was made for those who want to have more descriptive ||
|| error messages from Turbo Pascal programs. The error messages ||
|| will be sent to the standard DOS output file. The "EndWait" unit ||
|| is installed for version 5 of the compiler. ||
|| ||
|| MODIFICATION HISTORY: ||
|| 8905.31 Naoto Kimura ||
|| Original release ||
|| 9001.17 Naoto Kimura ||
|| Modified to use some of the lower level DOS system ||
|| calls to try to shrink code. ||
|| (The TPU file shrunk to slightly more than half the ||
|| original size) ||
|| 9004.08 Naoto Kimura ||
|| Rewrote parts in assembler to make more compact. ||
|| (The TPU file shrunk to less than half the original ||
|| size!) ||
|| 9005.11 Naoto Kimura ||
|| Added error message for version 5.5 of Turbo Pascal. ||
\*====================================================================*)
