Replace certain characters at the left of a string
REPLLEFT( <cString>, <cReplace|nReplace>, [<cSearch|nSearch>] ) -> cString
<cString> [@] Designates the string that is processed.
<cReplace|nReplace> Designates the character that replaces the character in <cSearch|nSearch> at the beginning of the <cString>.
<cSearch|nSearch> Designates the character at the beginning of <cString> that is replaced by <cSearch|nSearch>. The default value is a
The processed <cString> is returned.
REPLLEFT() can be used to exchange all leading characters in a string for any other selected character.
. The return value of this function can be suppressed by implementing CSETREF() to save space in working memory.
. Replace the leading spaces with zeros: ? REPLLEFT(" 1234", "0") // "001234" . Replace the leading zeros with spaces: ? REPLLEFT("001234", " ", "0") // " 1234" . Replace only the leading spaces: ? REPLLEFT(" 1 ", "0") // "001 "
REPLLEFT() is compatible with CT3’s REPLLEFT().
