SPELL CHECK TEXT


SPELL CHECK TEXT ( text ; errPos ; errLength ; checkPos ; arrSuggest )

Parameter	Type	Description
text	Text	Text to check
errPos	Longint	Position of first character of unknown word
errLength	Longint	Length of unknown word
checkPos	Longint	Start position for check
arrSuggest	Text array	List of suggestions

Description

The SPELL CHECK TEXT command checks the contents of the text parameter beginning from the checkPos character and returns the position of the first unknown word it finds (if any).

This command returns the position of the first character of this unknown word in errPos and its length in errLength. The arrSuggest array receives the correction suggestion(s) proposed by the spell checker.

If the check starts without error and an unknown word is found, the OK system variable is set to 0. If an initialization error occurs during the check, or if no unknown words are found, OK is set to 1.

Note OS X: Under OS X, when the native spell checker is enabled, this command does not support grammar correction.

Example

We want to count the number of possible errors in a text:

 $pos:=1

 $errCount:=0

 ARRAY TEXT($tErrors;0)

 ARRAY TEXT($tSuggestions;0)

 Repeat

    SPELL CHECK TEXT($myText;$errPos;$errLength;$pos;$tSuggestions)

    If(OK=0)

       $errCount:=$errCount+1 // count any errors

       $errorWord:=Substring($myText;$errPos;$errLength)

       APPEND TO ARRAY($tErrors;$errorWord) // array of errors

       $pos:=$errPos+$errLength  //continue check

    End if

 Until(OK=1)

  // In the end $errCount=Size of array($tErrors)
