COMPILER system handle

A handle to information on a preceding COMPILE statement.

Syntax

COMPILER [ :attribute ]

attribute

Specifies an attribute of the COMPILER system handle.

Attributes

CLASS-TYPE attribute	ERROR attribute	ERROR-COLUMN attribute
ERROR-ROW attribute	FILE-NAME attribute	FILE-OFFSET attribute
MULTI-COMPILE attribute	STOPPED attribute	TYPE attribute
WARNING attribute

Example

The input for example procedure is as input a comma-separated list of source files. It compiles each of these procedures. If a compilation error occurs, an appropriate message is written to the compile.msgs file.

r-cmpchk.p

/* Compile a series of source files passed in a comma separated list. */ DEFINE INPUT PARAMETER sources AS CHARACTER. DEFINE VARIABLE entry-num AS INTEGER. /* If the output file already exists, delete it. (If this results in an error, ignore the error.) */ OS-DELETE "compile.msgs". DO entry-num = 1 TO NUM-ENTRIES(sources): COMPILE VALUE(ENTRY(entry-num, sources)) SAVE. IF COMPILER:ERROR THEN DO: OUTPUT TO "compile.msgs" APPEND. MESSAGE "Compilation error in" COMPILER:FILENAME "at line" COMPILER:ERROR-ROW "column" COMPILER:ERROR-COL. OUTPUT CLOSE. END. END.

Notes

If a compilation is successful, the COMPILER:ERROR attribute is set to FALSE.
After a COMPILE statement, check the COMPILER:ERROR and COMPILER:WARNING attributes to determine whether the compilation was successful. If the value of ERROR is TRUE, you can use the FILE-NAME to determine in which source file the error occurred. You can use either the ERROR-ROW and ERROR-COLUMN attributes or the FILE-OFFSET attribute to determine where in the source file an error occurred. You can use this information to compose a message to display or write to a log file. To find the specific error and warning messages, check the ERROR-STATUS handle.
The TYPE attribute returns the widget type, PSEUDO-WIDGET.
