REMCOLS

The REMCOLS function removes specified columns from every line of a multiline TEXT value. The function returns a multiline text value that includes only the remaining columns.

Columns refer to the character positions in each line of a multiline TEXT value. The first character in each line is in column one, the second is in column two, and so on.

Return Value

TEXT or NTEXT

REMCOLS always returns a TEXT value that has the same number of lines as text-expression, though some of the lines may be empty.

Syntax

REMCOLS(text-expression start [length])

Arguments

text-expression

The text expression from which the specified columns should be removed. When text-expression is a multiline TEXT value, the characters in the specified columns are removed from each one of its lines.

When you specify a TEXT expression, the return value is TEXT. When you specify an NTEXT expression, the return value is NTEXT.

start

An INTEGER, between 1 and 4,000, representing the column position at which to begin removing columns. The column position of the first character in each line of text-expression is 1. When you specify a starting column that is to the right of the last character in a given line in text expression, the corresponding line in the return value will be identical to the given line.

length

An INTEGER representing the number of columns to be removed. When you do not specify length, REMCOLS removes only the starting column. When you specify a length that exceeds the number of characters that follow the starting position in a given line in text expression, the corresponding line in the return value will include only the characters that precede the starting column.
