In order to display statistical results in the form of frequency tables and histograms the names of the tables must be declared. The header of the declaration is TABLES. It must be followed by one or more declarations of the form:
<variable identifier> : <table identifier>;
<variable identifier> is the name of a simple real variable
whose values through time are to be tabulated.
<table identifier> is the identifier assigned to the table.
The tabulation of values must be commanded by the user with the TAB procedure (see 7.22).
