Purpose

Function to perform substring extraction (double byte character sets)

Syntax

SUBSTRC(<expC> | <memofield>, <expN1> [,<expN2>])

Description

The SUBSTRC() function extracts a substring from <expC> or <memofield> starting at position <expN1> of width <expN2>. If <expN1> is negative, the extraction starts from the right side of the string. If <expN2> is omitted, a substring will be extracted up to the end of <expC>. When used in conjunction with the AT_C() function, the SUBSTRC() function is very useful for extracting selected information from character strings.

Example

cDBSubString = substrc(cDBString, nStart, nWidth)
