Back to Script Statements and Keywords (page 219).
Let
The let statement has been created as a complement to the Set (page 264) statement, used for defining
Script Variables (page 273). The let statement, in opposition to the set statement, evaluates the expression
on the right side of the ' =' before it is assigned to the variable.
The word let may be omitted, but the statement then becomes a control statement. Such a statement without
the keyword let must be contained within a single script row and may be terminated either with a semicolon
or end-of-line.
The syntax is:
let variablename=expression
Note that the word let may be omitted.
Examples:
Set x=3+4;
Let y=3+4
z=$(y)+1;
$(x) will be evaluated as ' 3+4 '
$(y) will be evaluated as ' 7 '
$(z) will be evaluated as ' 8 '
Let T=now( );
$(T) will be given the value of the current time.

Load
The load statement loads Fields (page 169) from a typed ASCII file, from data defined in the script, from a
previously loaded table, from the result of a following select statement or by generating data automatically.
The general syntax of the load statement is:
load [ distinct ] *fieldlist
[( from file [ format-spec ] |
from_fieldfield [format-spec]
inline data [ format-spec ] |
residenttable-label |
autogenerate size )]
[ where criterion ] | while criterion ]
[ group_by fieldlist ]
[order_by field [ sortorder ] { , field [ sortorder ] } ]
where:
distinct is a predicate used if only the first of duplicate records should be loaded.
*fieldlist ::= ( * | field { , field } )
246
A list of the fields to be loaded. Using * as field list indicates all fields in the table.
