Translate (String function)
The Translate method takes a string or longstring input and outputs a copy of it in which any of the input characters that are specified in a character mapping object are replaced with the characters to which they are mapped by the object.
Translate has many similarities to the Sirius function $LSTR_TRANSLATE, which is described in the Sirius Functions Reference Manual.
The Translate method takes a CharacterMap object as input. A CharacterMap object maps In ("input table") characters to Out ("output table") characters.
Translate syntax
%outStr = string:translate(charMap)
Syntax Terms
- %outStr
- A string or Longstring to receive the translated input string.
- string
- The input string or Longstring.
- charMap
- A CharacterMap object variable which indicates the output characters to which specified input characters are to be mapped.
Usage Notes
- For information about constructing a CharacterMap object, see CharacterMap New constructor.
Examples
In the following request, a's are translated to B's, and c's are translated to d's, as dictated by the character mapping in %map:
Begin
%map is object characterMap
%ls is longstring
%map = new(in='ac',out='Bd')
%ls = 'aaaccc'
printtext {~} = '{%ls:translate(%map)}'
End
The result is:
%ls:translate(%tr) = 'BBBddd'
