Targeted Text statements

The AuditText, PrintText, and TraceText statements are abbreviated forms of the Text and Html statements. They have the same effect as the Text Audit, Text Print, Text Trace, Text Return, and Text Set statements respectively.

The AuditText, PrintText, and TraceText statements are available in Sirius Mods 7.2 and later.

In addition the SetText statement, which is available in Sirius Mods 7.8 and later, uses the same syntax as AuditText, PrintText, and TraceText to set a target variable.

The ReturnText statement, which is available in Sirius Mods 7.8 and later, uses the same syntax as AuditText, PrintText, and Tracetext to return a string value from a User Language function or property Get method.

The AuditText, PrintText, and TraceText keywords are simply a merging and reordering of Text Audit, Text Print, and Text Trace to emphasize the principle action. The lone difference between the former and latter forms is that former cannot be used if you want to include other Html/Text options, as in:

  text noexpr print The set is {2, 3, 5, 8, 13, ...}

However, as of Sirius Mods 7.8, certain Text statement directives can be placed after a tilde character inside curly braces in any of the targeted text statements. For example

 setText %ls = {~nocont}---{$time}---

sets %ls to the current time embedded in hyphens. Because the ~nocont directive was specified, the terminating hyphen is not treated as a continuation character. The tilde directives that are allowed in targeted text statements are:

~exprE: Sets the expression end characters. This directive must be followed by a space and then the expression start characters as in {~expre >} which sets the expression end characters to a single greater than sign. ~exprE can also be written as ~exprEnd. Note that the ~exprE directive must be ended by the expression end characters in effect before the ~expre directive is processed.; Sets the expression start characters. This directive must be followed by a space and then the expression start characters as in {~exprs <} which sets the expression start characters to a single less than sign. ~exprS can also be written as ~exprStart.
~noCont: Indicates that a trailing hyphen is not treated as a continuation character. ~noCont can also be written as ~noContinuations.
~noEll: Indicates that a trailing ellipses (...) is not treated as partial line indicator. Because it makes no sense to end a SetText or ReturnText with ellipses, this is the default for those two statements so, while allowed, this directive is completely unnecessary for SetText and ReturnText. ~noEll can also be written as ~noEllipses.
~noExpr: Indicates that no expressions are to be processed after the directive and that everything after the ~noExpr directive is treated as literal text. No further tilde directives will be processed after a ~noExpr. ~noExpr can also be written as ~noExpressions.
~raw: The same as specifying all of ~noCont, ~noEll, and ~noExpr. Note that this is slightly different from the Raw directive on the Text/Html statement which also implies NoDum/NoDummy. This is because dummy string substitution applies to lines before they are parsed up so that dummy string substitution would already have happened in any single line Text statement before the ~raw directive was processed.

As would be expected, AuditText sends its output to the Model 204 audit trail, PrintText sends its output to the current output stream (output terminal or use dataset), and TraceText sends its output to the current trace targets. These statements are the recommended/preferred alternatives to the traditional Audit, Print, and Trace statements. The reason they are recommend over these other statements is because they are more flexible and have more consistent behavior.

All text not inside of curly braces in an AuditText, PrintText, or TraceText statement is considered to be literal text. For example, the following will display "Suit the action to the word, the word to the action" on the primary output stream:

  printText Suit the action to the word, the word to the action

Values of variables and calculated values, can be placed inside of curly braces to that the value of what's inside the braces is displayed. For example, the following would display "%i = 22, %j = 33, %i * %j = 726":

  %i = 22
  %j = 33
  printText %i = {%i}, %j = {%j}, %i * %j = {%i * %j}

Any valid expression is allowed inside the curly braces, including those that contain parentheses, $functions, and method calls. For example, the following would display "%i = 22, %j = 33, (%i + %j):toPower(3) = 166375":

  %i = 22
  %j = 33
  printText %i = {%i}, %j = {%j}, (%i + %j):toPower(3) = {(%i + %j):toPower(3)}

If a single tilde (~) character is found inside curly braces, it must be followed (possibly with some intervening text) with an expression inside curly braces. The {~} would then be replaced with the literal contents of the following curly braces. For example, the following would display "%i = 22, %j = 33, (%i + %j):toPower(3) = 166375":

  %i = 22
  %j = 33
  printText {~} = {%i}, {~} = {%j}, {~} = {(%i + %j):toPower(3)}

As of Sirius Mods 7.8 one can also use a ~= directive as a shorthand for {~}={expression} as in whih would display "%i=22, %j=33, (%i + %j):toPower(3)=166375". Note that in the directive, spaces are optional after the equals sign and the output produces no spaces before or after the equals sign. If more control of spacing is required, the {~} directive should be used.

One common issue with the {~} syntax is that one might feel that a variable used as a subscript (perhaps for an ArrayList), should be replaced by its value. For example, if one had:

  b
  %i is float
  %j is float
  %al is arraylist of float
  %al = list(13, 17, 30)
  for %i from 1 to %al:count
     printText {~} = {%al(%i)}
  end for
  end

One might expect the following to be displayed:

  %al(1) = 13
  %al(2) = 17
  %al(3) = 30

But, instead, the following is displayed:

  %al(%i) = 13
  %al(%i) = 17
  %al(%i) = 30

One way to deal with this is to simply "manually" build the part before the value:

  for %i from 1 to %al:count
     printText %al({%i}) = {%al(%i)}
  end for

Another way, is to simply also show the subscript value:

  for %i from 1 to %al:count
     printText {~} = {%i}, {~} = {%al(%i)}
  end for

This ends up displaying:

  %i = 1, %al(%i) = 13
  %i = 2, %al(%i) = 17
  %i = 3, %al(%i) = 30

SetText statement

The SetText statement works much the same as AuditText, PrintText, and TraceText, but is used to set a variable instead of outputting a string. The syntax of the SetText statement is:

  setText %variable = string

Where

string: is a literal string with expressions inside of curly braces, just as is used in the Text statement.

For example, the following

  setText %x = Patriotism is the last refuge of the scoundrel

sets %x to the literal string "Patriotism is the last refuge of the scoundrel". And the following:

  setText %x = The sum of %x and %y is {%x + %y}

Sets %x to the literal string "The sum of %x and %y is " followed by the sum of %x and %y.

The target of SetText can be a simple variable, a class variable, a class property, or a collection member (which is really just a special kind of class property). For example, the following:

  %toke        is object stringTokenizer
   ...
  setText %toke:string = Once upon a time

sets the String propert of a StringTokenizer object to the literal string "Once upon a time". A single blank after the equals sign after a SetText is ignored so can be used for readability, but is not required. That is

  setText %str =Once a jolly swagman camped by a billabong

and

  setText %str = Once a jolly swagman camped by a billabong

both set %str to "Once a jolly swagman camped by a billabong". Any additional blanks beyond the first one, are treated as part of the literal source string.

Continuations are treated in the normal way, that is the text continues from the first non-blank character on the next line. Tip: if you need to include blank characters from the next line, use {} (a null expression) to indicate the start of the continuation. For example:

  setText %str = Once a jolly swagman camped by:-
                 {}   a billabong

will set %str to:

  Once a jolly swagman camped by:   a billabong

However, trailing blanks before a continuation are not stripped so one can accomplish the same thing by putting extra blanks at the end of the first SetText line:

  setText %str = Once a jolly swagman camped by:   -
                 a billabong

If you need to terminate the string with a hyphen add the {} to the end of a line. For example:

  setText %str = ------------{}

will set %str to:

  ------------

You can also use the ~noCont directive to indicate that a trailing hyphen is not to be treated as a continuation character:

  setText %str = {~nocont}------------

ReturnText statement

The ReturnText statement works much the same as AuditText, PrintText, and TraceText, but is used to return a string value in a User Language function or property Get method instead of outputting a string. The syntax of the ReturnText statement is:

  ReturnText string
