	Problems can occur when using RUN PROC if there are too many or too few lines of data in the procedure file. If GLTRANSF were expecting two lines of input in the EOM procedure above, and only one is provided, it would take the next line of the procedure file (the LOAD NEWMONTH command) and try to use it for input. If numeric data is required, a conversion error will occur. If you suspect this type of error has occurred, type CLEAR PROC to end the procedure before things get worse. If the procedure continues, it would execute the RUN command (the one after LOAD NEWMONTH) next. This would execute the program currently in memory, which would still be GLTRANSF (since the LOAD NEWMONTH command was used for data and caused the conversion error when GLTRNASF was run the first time). Around this time, the operator would probably be thoroughly confused; they would now be seeing the menu from GLTRANSF which they have never had to respond to before because the response has always been included in the procedure file. So, typing CLEAR PROC at the first error would save them from all this additional confusion.
