Abstract

When converting files created by other programs, such as DIF* or SYLK**, there are many cases that the resultant files cannot be handled by the file manager of the Merge with file function in DisplayWrite 3***. Some examples are: the converted file may contain more than 100 fields or the sum of all field lengths is greater than 2000. One solution is to have each conversion program check for these error conditions and stop processing when an error is detected. This involves extensive coding work since each conversion processes in an independent environment. In accordance with the new method, all the error-checking logic is delayed until merge is run. The file manager then detects the errors. The main advantage is that the extensive error checking logic need not be duplicated in each conversion.

This involves extensive coding work since each conversion processes in an independent environment. In accordance with the new method, all the error- checking logic is delayed until merge is run. The file manager then detects the errors. The main advantage is that the extensive error checking logic need not be duplicated in each conversion. This results in better performance because the buffer allocation algorithm tries to get all available memory. * Trademark of Software Arts Products Corporation. ** Trademark of Microsoft Corporation. *** Trademark of IBM Corporation.
