FOREACH()

FUNCTION: foreach([<object>/]<attribute>,<string>[,<begin>, <end>])

Maps a function onto a string.

Each character in <string> has the user-defined function of the first argument performed on it; the character is passed to the function as %0. The results are concatenated. If <begin> and <end> are specified, only the characters between <begin> and <end> are parsed, other characters are concatenated as they are. This allows a rudimentary form of tokens and speeds up the evaluation greatly if tokenizing is your purpose.

Examples:

> &add_one me=[add(%0,1)] > say [foreach(add_one, 54321)] You say, "65432"

> &add_one me=[add(%0,1)] > say [foreach(add_one, This adds #0# to numbers in this string,#,#)] You say, "This adds 1 to numbers in this string."
