NIPO ODIN Version 5.17
*RANGE
Purpose
Specifies a value range for numerical questions.
Syntax
*RANGE <[n1|expression [TO n2|expression]]>[;n3 [TO n4];...]
Description
This command specifies a range for numerical questions and numerical fields in a *FORM question. You can specify a start value and an end value for the range by separating the two values with the keyword TO. Multiple values can separated by a semicolon (;). Instead of a value, an expression may also be used.
Remarks
You can only use an incremental range (1 TO 5 rather than 5 TO 1).
A semicolon must be used to separate two ranges. When using a comma, the system interprets this as a column-code reference.
The argument TO must be used to separate the extremes within a range. The dash (-) is interpreted as a minus sign and should not be used.
Arguments
n1
The start value of the range.
n2
The end value of the range.
expression
An expression of which the result will be used as the start or end value.
