pc.text.extract

Processing Code/Restore Processor, Releases: AP

Text extraction function.

Syntax

t{startcolumn,}length

Description

provides a facility for extracting any number of characters from an attribute, starting at the position specified in 'startcolumn', for a length of 'length'.

If the startcolumn parameter is not specified, the extraction begins from the same end of the string as the justification attribute (9), either l (left) or r (right).

Columns are always counted from left to right, regardless of the justification specified in the attribute-defining item.

Both parameters must be numeric.

Example

t3,10

This extracts 10 characters, beginning from the 3rd position of the string.
