# SYSTEM LIMITS

This section documents some relevant limits when using Dataplot. Note that many of these limits can be set (in the file DPCOPA.INC) before Dataplot is compiled on a specific system. The limits below are the default values, but the limits for your specific system may be set differently.

1. MAXOBV = 2,000,000

Defines the maximum number of observations for a single variable. This is the parameter most likely to be modified before Dataplot is compiled. It will typically be in the range 1,000,000 to 2,000,000.

2. MAXOBW = 10*MAXOBV

Defines the total size of the data work space. Note that the DIMENSION command can be used to re-allocate between rows and columns with the restriction that the maximum number of rows cannot exceed MAXOBV.

3. MAXPOP = 2*MAXOBV

Defines the maximum number of points on a plot.

4. MAXNME = 50000

Define the maximum number of names (variables, parameters, strings, matrices).

5. MAXSTR = 255

Defines the maximum number of characters in a single command line.

6. MAXEDC = 24*MAXOBV

Defines the maximum number of characters that the EDIT/FED command can accomodate.

7. MAXEDL = 25000

Defines the maximum number of lines for the EDIT/FED command.

8. MAXCMP = 35

Defines the maximum number of coefficients in multilinear regression.

9. MAXLIS = 200 MAXCIS = 255

Define the maximum number of lines/columns in the LIST/SAVE table.

10. MAXLIL = 20000
MAXCIL = 255

Define the maximum number of lines/columns in the LOOP table.

11. MAXLIP = 20

Define the maximum number of lines in the REPLOT table.

12. MAXPM = 200

Define the maximum number of pixmaps that can be saved.

13. MAXTOM = 46*MAXOBV/3

Define the maximum size (rows times columns) for a matrix. Note that the DIMENSION MATRIX command can be used to specify the allocation between rows and columns in the matrix.

14. Define the following plot control component dimensions:

 MAXTC = 100 = the maximum number of tic marks on an axis. MAXLG = 100 = the maximum number of legends. MAXBX = 100 = the maximum number of boxes. MAXAR = 100 = the maximum number of arrows. MAXSG = 100 = the maximum number of segments. MAXLN = 100 = the maximum number of line traces. MAXCH2 = 100 = the maximum number of character traces. MAXFL = 100 = the maximum number of region fills. MAXPT = 100 = the maximum number of patterns. MAXSP = 100 = the maximum number of spikes. MAXBA = 100 = the maximum number of bars. MAXRE = 100 = the maximum number of regions. MAXTX = 100 = the maximum number for the text command. MAXSUB = 10 = the maximum number of subregions. MAXGRP = 5 = the maximum number of group label variables. MAXGR2 = 40 = the maximum number of characters for a group label. MAXGLA = MAXOBV/100 = the maximum number of levels for a group label. MAXCNL = 100 = the maximum number of contour labels.

15. MAXCH = 200

Define the maximum number of characters in a text string for a title or label.

16. MAXLG2 = 200

Define the maximum number of characters in a legend.

17. MAXF1 = 50,000

Define the total number of characters for all strings/functions.

18. MAXF2 = 500

Define the maximum number of strings/functions.

19. MAXF3 = 500

Define the maximum number of characters printed for the last model fitted.

20. MAXRCL = 9999

Define the maximum number of characters that can be read from a single record in a data file.
