The pad(...) function has two variations, not counting syntax variations. It makes a copy of a String value with zero or more characters appended to or prefixing the source-string to produce a value with a specified minimum length.
Syntax:
pad( source-string, pad-character, length )
pad( source-string, pad-character, length, prefix )
source-string.pad( pad-character, length )
source-string.pad( pad-character, length, prefix )
| Parameter |
Description |
| source-string |
The String from which to copy. |
| pad-character |
The pad character which will be added repeatedly until the desired length is achieved. The pad-character parameter is actually a String value. If a null or empty String value is given then the result is the unaltered source-string. If the length of the pad-character String is greater than one then the first charcter in the String is used. |
| length |
The minimum desired length of the result String. |
| prefix |
If prefix is true, then the function adds characters at the beginning of the source-string instead of the end. |
