FMTDW(), FMTDWS()

The FMTDW() function performs data formatting according to a format template based on display width. The FMTDWS() function is identical to FMTDW() except that it works on each element of a dynamic array in turn, returning the result in a similarly delimited dynamic array.

Format

FMTDW(expr, fmt.spec)

FMTDWS(expr, fmt.spec)

where

expr	evaluates to the data to be formatted

fmt.spec

evaluates to the format specification.

The FMT() function sets the STATUS() function value to indicate whether the operation was successful. Possible values are

0	Successful formatting.

1	Data to format was too long or invalid for the format specification.

2	The format specification was invalid.

Operations that result in a non-zero STATUS() value return expr as the function result.
