What is XTAB? |
A Perl based program used primarily to produce cross-tabulations
of data elements located within flat files. Output is printed,

- spreadsheet compatable) files as well. Idea being these files
can be inputted to an HTML editor or Spreadsheet for further
processing, formatting, and or graphic generation. |

What is a cross-tabulation? |
In its simplest form, a cross-tabulation is a two dimensional
table consisting of rows (a stub) and columns (a spread). Each
cell in the table is a count of the number of the occurrences
of each particular stub and spread variables values. |
|
How is a cross-tabulation generated? |
A cross-tabulation is generated by reading a file one record
at a time, calculating the appropriate array cell to increment
from the stub and spread values, and finally printing the results. |

into a proper Perl program. That Perl program is executed to
produce the desired results. |

What is required to run XTAB? |
A unix signon, access to Perl 5.0, the ability to create
a text file. |

is and how to define the parameters for its contents. In its
elementary case the XTAB user is not programming, but specifying
parameters. The sophisticated user is just more powerful. |
