Assigning a Procedure variable

• a procedure known in the project.
  The following syntax must be used:
  
  <Name of Procedure variable> = <Procedure>
  
  For example:
  
  p is procédure
  p = CheckExistence
  
  
  Remarks:
  • The <Procedure> parameter must correspond to a procedure found in the project.
  • The <Procedure> parameter must not be enclosed in quotes.
  • The <Procedure> parameter must not be followed by call parameters.
  • The <Procedure> parameter must not correspond to the name of an internal procedure.
• Versions 19 and later
  a procedure dynamically compiled by Compile.
  The following syntax must be used:
  

  <Name of Procedure Variable> = Compile(<Procedure Code>)
  
  or
  
  <Name of Procedure Variable> =
  Compile(<Procedure Name>, <Procedure Code>)

  
  For example:
  

  p is procédure
  p = Compile("RESULT n1 + n2")
  

  
  Remarks:

  • If the name of the Procedure is specified, the Procedure can also be executed by the functions Execute and ExecuteProcess.
  • By default, the procedure dynamically compiled is a global procedure. To define a local procedure, you muse use the syntax defining the name of the procedure in order to specify the requested element in the name of the procedure.

  The following syntax must be used:
  

  <Name of Procedure Variable> = Compile(<Procedure Code>)
  
  or

  For example:
  

  p is procédure
  p = Compile("RESULT n1 + n2")

  • By default, the procedure dynamically compiled is a global procedure. To define a local procedure, you muse use the syntax defining the name of the procedure in order to specify the requested element in the name of the procedure.

• a class method.
  The following syntax must be used:
  
  <Name of Procedure Variable> = <Method>
  
  Remarks:
  • The <Method> parameter must correspond to a method of current class or to a method of base class.
  • If <Method> is a method of instance, the code must be run in a method of instance of the class containing the method or in a derived class.
  Remarks:
  • The <Method> parameter can correspond to a method of the current class or of a base class.
  • Versions 26 and later
    If <Method> is an instance method, the following notation should be used <OneObject>.<Method>.
    New in version 26
    If <Method> is an instance method, the following notation should be used <OneObject>.<Method>.
    If <Method> is an instance method, the following notation should be used <OneObject>.<Method>.

• You also have the ability to copy the procedures of a Procedure variable into another Procedure variable. The syntax is as follows:
  
  <Name of Destination Procedure Variable> =
  <Name of Source Procedure Variable>
  
  Remark: It is a copy of variable: any modification made to one of the variables will not be applied to the other one.
• You also have the ability to find at runtime a procedure identified by its name and to assign it to a Procedure variable. In this case, the following syntax must be used:
  
  <Name of Procedure Variable> = <Procedure Name (with quotes)>
  
  Remark: Using this syntax to assign a Procedure variable takes quite a long time because the name of the procedure is sought in all the procedures of the project.
• Assignment by reference (<- operator)
  The assignment by taking reference forces the destination element to reference the same data area as the source element.
  Therefore, a Procedure variable can be handled by another Procedure variable. To do so, we must retrieve a reference on the Procedure variable itself. Any future modification made to one of the variables will be applied to the other one.
  The following syntax must be used:
  
  <Name of Destination Procedure Variable> <- <Name of Source Procedure Variable>

Multiple assignment of a Procedure variable

Versions 18 and later
Remark: To delete a procedure from a Procedure variable, you have the ability to use the "-=" operator.

For example:

p is procédure
p += Proc1
p += Proc2
 
...
 
p -= Proc2

New in version 18
Remark: To delete a procedure from a Procedure variable, you have the ability to use the "-=" operator.

For example:

p is procédure
p += Proc1
p += Proc2
 
...
 
p -= Proc2

Remark: To delete a procedure from a Procedure variable, you have the ability to use the "-=" operator.

For example:

p is procédure
p += Proc1
p += Proc2
 
...
 
p -= Proc2

Passing Procedure parameters by reference or by value

• to pass parameters by reference:
  
  PROCEDURE <ProcedureName>(MyProcedure is Procedure)
• to pass parameters by value:
  
  PROCEDURE <ProcedureName>(LOCAL MyProcedure is Procedure)

• call while specifying a procedure known by the project: the following syntax must be used:
  
  ProcedureName(<Project Procedure>)
  
  Remarks:
  • The <Project Procedure> parameter must correspond to a procedure found in the project.
  • The <Project Procedure> parameter must not be enclosed in quotes.
  • The <Project Procedure> parameter must not be followed by shortcuts.
• call while specifying a class method: the following syntax must be used:
  
  ProcedureName(<Method>)
  
  Remarks:
  • The <Method> parameter can correspond to a method of the current class or of a base class.
  • Versions 26 and later
    If <Method> is an instance method, the following notation should be used <OneObject>.<Method>.
    New in version 26
    If <Method> is an instance method, the following notation should be used <OneObject>.<Method>.
    If <Method> is an instance method, the following notation should be used <OneObject>.<Method>.
• call with reference to a procedure variable: the following syntax must be used:
  
  ProcedureName(<Name of Procedure variable>)
• call with search at runtime for a procedure identified by its name: the following syntax must be used:
  
  ProcedureName(<Procedure name (with quotes)>)

Call to the procedures found in a Procedure variable

• If the Procedure variable contains a single procedure, the call returns the return value of the procedure.
• If the Procedure variable contains several procedures, the call returns the return value of the last procedure called.
