'source string ' The string value to be formatted.
'format string ' The string value that determines the format of the source string value.
The characters below are placeholders or modify a corresponding character:
The A character, used for Auto Skip in an Edit field, is ignored.
Numbers define the repetition of the preceding format character. If a format character does not precede the number it will repeat the number of times the X format character appears.
For example: The format of 2@3U5 is the same as XX@@@UUUUU.
The backslash, \, character lets you define an operator as a fixed character.
For example: '('abcd','2@3A\U\5\A') returns 'ab@@@U5A'
If the total length of the character placeholders provided in the format string is smaller than the source string length, the remaining characters are truncated.
