## CAPACITY LIMITS

Ploticus has these capacity limitations.`` They may be raised or lowered by modifying `pl.h`.``

  Data storage capacity: 1 million characters (data is stored as text).``

  Max total number of data fields: 200,000

  Max length of a line in a ploticus script: 3000 chars before & after variable evaluation

  Maximum total number of lines in current proc and all #saved procs: 5000

  Max length of variable contents: 250 chars

  Max length of data field: 250 chars

  Max length of input data record: 2998 chars

  Max length of field names and variable names: 38 chars

  Max number of values for rangebar percentile computation: 100,000

  Max number of points for lineplot, scatterplot or curvefit result curve: 50,000.``

  Max number of points for rangesweep: 33,333.``

  Max number of scale categories in X: 100; in Y: 100.``

  Max number of points from which to compute a moving average or regression curve in proc curvefit: 5000. Bspline curve: 100.``

  Max number of points in polygon (including line plot w area under curve filled): 1000

Proc Tabulate limits:

  max number of proc tabulate rows 200;

  max number of proc tabulate columns 200;

  max number of proc tabulate ranges 200;

  # of significant characters for differentiation during tabulation 38.``

## SYSTEM RESOURCES

By default, the max amount of CPU time allowed is 10 seconds, and any files created cannot be larger than 5,000,000 bytes. These limits are enforced using setrlimit(), and a core dump occurs when limits are exceeded. These limits may be modified using a config file or by modifying pl.h
