DDDriverStringCommands::CleanString
RJ TID SDC RC SE2

CleanString, for each char in string: if ((char .gt. 31) and (char .lt. 127)) keep it, otherwise turn it into a space


Fields: [ ]=Optional with Default Value
  1. sourceString
    sourceString (could come from a ^variable)


  2. resultVar
    the resultVar to place the result of the operation into


Examples:
  • C, cleanString, "a^Abcd", var
    variable 'var' should contain 'a bcd' after this is run (note that ^A is a Control-A, not the actual chars ^ and A)

DDDriverStringCommands::Compare
RJ TID SDC SE2

Compares two strings and returns an integer specifying the result of the comparison. The java version returns 'true' or 'false' as the result.

For java version, if the parameter 'regexMatch' is true, then the parameter 'dstString' is considered as regular expression.

Fields: [ ]=Optional with Default Value
  1. sourceString
    The source string (could come from a ^variable) to compare.


  2. dstString
    The destination string (could come from a ^variable) to compare.

    This is normally a simple string;
    But it could be a regular expression if the parameter 'regexMatch' is true. Do NOT forget the leading symbol ^ and the ending symbol $ if the whole string should be considered; Without them, if a sub-string of the 'sourceString' can match the regex pattern, then it is considered matched.

  3. resultVar
    the resultVar to place the result of the operation into


  4. [ regexMatch = false ]
    Indicates if the comparison is in regex way.

    This parameter is optional, the default value is false. If this is true, then the parameter 'dstString' should be provided with a regular expression. Else if this is false or not provided, the parameter 'dstString' will be treated as a normal string even if it is provided with a regular expression.

Examples:
  • C, Compare, "abc", "abcd", var
    variable 'var' should contain 'false'


  • C, Compare, "Hi, Hello World with happy", "[H|h]ello [W|w]orld", var, true
    variable 'var' should contain 'true', as sub-string "Hello World" of the source string "Hi, Hello World with happy" can match the regex pattern "[H|h]ello [W|w]orld"


  • C, Compare, "Hi, Hello World with happy", "^[H|h]ello [W|w]orld$", var, true
    variable 'var' should contain 'false'. With leading symbol ^ and ending symbol $, it is expected that the whole string of "Hi, Hello World with happy" matches with the regex pattern "^[H|h]ello [W|w]orld$", but it does not unfortunately.
