Purpose
Function to evaluate an expression and return the result as a string
Syntax
ETOS(<expr> [, <expN>])
See Also
CAST(), DTOC(), DTOS(), LTOS(), MTOS(), RTOS(), SET STRICT, STR(), TOSTRING()
Description
The ETOS() function evaluates the expression in <expr> and returns the result as a string. The <expr> can be any valid string, date, datetime, logical or numeric expression.
Where <expr> is a date or datetime expression, the string returned will conform to the current SET DATE, SET SEPARATOR, SET SECONDS and SET CENTURY settings, in the same format as DTOC() or TTOC().
The optional <expN> is used to specify the length of the string returned. If the length is shorter than that required by <expr>, strings, dates and datetimes are truncated to the right and numerics truncated to the left.
Example
? etos({03/29/2003}) 03/29/2003 ? etos({03/29/2003},5) 03/29 ? etos(10 * 10) 100 ? etos(0.45,3) .45 ? etos("Hello" + " " + "World") Hello World ? etos("Hello" + " " + "World",5) Hello ? etos(.F.) F
