C_TEXT

version 3

C_TEXT ({method; }variable{; variable2; ...; variableN})

The C_TEXT command casts each specified variable as a Text variable.

The first form of the command, in which the optional method parameter is NOT passed, is used to declare and type any process, interprocess or local variable.

Note: This form can be used in interpreted databases.

The second form of the command, in which the optional method parameter IS passed, is used to predeclare to the compiler the result and/or the parameters ($0, $1, $2 etc) for a method. Use this form of the command in order to skip the Typing variables phase while compiling a database, saving compilation time.

WARNING: The second form cannot be executed in interpreted mode. For this reason, if you are using this syntax, keep it in a method that is not executed in interpreted mode. The name of this method must start with "COMPILER."

Advanced Tip: The syntax C_TEXT(${...}) allows you to declare a variable number of parameters of the same type, under the condition that these are the last parameters for the method. For example, the declaration C_TEXT(${5}) tells 4D and the compiler that starting with the fifth parameter, the method can receive a variable number of parameters of that type. For more information, see the Count parameters command.

See examples in the section Compiler Commands.
