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 |
