Is size of database limited?

From: Jenny <zheng.22@osu.edu> Subject: Is size of database limited? Date: Sat, 09 Jan 1999 16:02:39 -0800 Dear NONMEM uses, I have run in problems of size limitation of data file. I am using an MS-DOS window running under Microsoft window 98, with Microsoft PowerStation Fortran. I wrote a $PRED abbreviation code, and I have 20 data items and 1176 data records. First, I can only use at most 18 data items, otherwise it will give error message: " AN ERROR WAS FOUND ON LINE 35 AT THE APPROXIMATE POSITION NOTED: F=DOSE/UVOL*EXP (-K1*TIME) THE CHARACTERS IN ERROR ARE: F 236 DATA ITEM MAY NOT BE CHANGED WITH THIS VALUE OF ICALL RETURN CODE 4" After reduced to any 18 data items, the program runs. In the output, "NO. OF DATA RECS. IN DATA SET: 1176" which is right, but all the scatter plots were truncated to 944 or 900 records. Dos any one know how can change source code to make it works? Thank you! Jenny
