The WRITE procedure assigns data to an output file. Syntax: WRITE( [[file_variable, ]]{expression},... [[,ERROR := error-recovery]] ) The 'file_variable' is the name of the file variable associated with the output file. If you omit the name of the file, the default is OUTPUT. The 'expression' is an expression whose value is to be written; multiple output values must be separated with commas. An output value must have the same type as the file components; however, values written to a TEXT file can also be expressions of any ordinal, real, or string type. The 'error-recovery' specifies the action to be taken if an error occurs during execution of the routine. By default, after the first error, the error message is printed and execution is stopped. The file (unless it is a random-access by key file) must be in generation mode before WRITE is called; it remains in that mode after WRITE has executed. By definition, a WRITE statement to a nontext file performs an assignment to the file buffer variable and a PUT statement for each output value. For nontext files, the types of the output values must be assignment compatible with the component type of the file. See the "Compaq Pascal Language Reference Manual" for a complete description of the WRITE procedure.
