Purpose

Function to perform 'C' style picture formatting

Syntax

PRINTF(<expC>, <exp1> [,<exp2>...])

See Also

ETOS(), FPRINTF(), SPRINTF(), TOSTRING()

Description

The PRINTF() function displays a string including one or more parameters, <exp1> [,<exp2>...], formatted according to the 'C' style options specified in <expC>. Each formatting sequence is applied to the corresponding parameter in the parameter list from left to right.

Formatting option	Description
%s
%d
%f
%y
%t
%T
%l
%L

Example

// When %s is specified, the corresponding argument is converted to 
// character format (similar to specifying etos()).
// Widths correspond to the default values, e.g. numerics are 10
printf('It is %s, %s to be more precise\n',year(date()),datetime())
printf('The value of pi is %s\n',pi())
printf('They cost %s per %-s\n',$99,100)
printf('Logicals can be %s or %s\n',.T.,.F.)
// Formatting characters can contain a width, which will left pad with spaces 
printf('Right-justify and pad left: %10s this\n','Like')
// Left justify by placing a '-' directly following the '%' character 
printf('Left-justify and pad right: %-10s this\n','Like')
// %d is for numerics
printf('It is %d\n',year(date()))
// %t and %T are for formating datetime data types.
printf('It is %d, %t to be more precise\n',year(date()),datetime())
printf('It is %d, %T to be even more precise\n',year(date()),datetime())
// %f is for floating point numerics
printf('The value of pi is %f\n',pi())
// Decimal places can also be specified for numerics (%d, %f) 
printf('The value of pi to two decimal places is %4.2f\n',pi())
// %y is for formatting currency data types
printf('They cost %y per %d\n',$99,100)
printf('They cost %y per %d\n',$99,1000)
printf('They cost %y per %d\n',$99,10000)
//%l and %L are for formatting logical datatypes.
printf('Logicals can be %l or %l\n',.T.,.F.)
printf('Logicals can also be %L or %L\n',.T.,.F.)
