The input for the example procedure is 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 NO-UNDO.
DEFINE VARIABLE entry-num AS INTEGER NO-UNDO.
/* 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:FILE-NAME "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.
