 Rivers Report 



APPENDIX E 



Runtime Errors 



Some errors can occur when you run the MRIS Rivers Report. Most of the time 

 these errors are minor and can be easily corrected. Common errors and possible 

 solutions are discussed below. 



I. Out of Memory 



The MRIS Rivers Report is a memory hog. 640K of memory is required and at least 

 512K of that memory must be available before running the program. If you get an out 

 of memory error the only option is to provide more memory. Try unloading some or 

 all of your TSR programs, (programs that are loaded and stay resident in memory, for 

 example SIDEKICK or TORNADO) or modifying your AUTOEXEC.BAT file so they are 

 not loaded automatically. 



Note: There is public domain software called "CONFIG.EXE" which can be used 

 to create more than one operating environment which can be easily loaded. 



Note: The presence of TSR programs may also be the reason for slow 

 performance. Again try unloading some or all of your TSR programs. 



II. File Opening Errors 



If any of the following messages appear at the bottom of the screen, one of two 

 problems has occurred. 



1) The file was not found, or; 



2) There are too many files open. 



PROC: OPEN_DATAB Line ???, open error xxxxxxxxxxxxxxxxxx Retry? (y/n) 

 PROC: RE_OPEN_IN Line ???, open error xxxxxxxxxxxxxxxxxx Retry? (y/n)
