Solving Program Errors

If you make an error in the program to create a form or an element in the form, a coded error message and program line containing the error will print when the form is executed. These error codes are defined in the ªError Codesº chapter.

To solve program errors, perform the following steps:

1.Locate the error message in the listing provided in the ªError Codesº chapter for a description of the error.

2.Analyze the related portion of the program to find the error.

3.Correct the error and reprint the file containing the program.

4.If the error persists or you cannot locate it in the program, use the debug parameter [/] in the Create command as described in the Error Codes chapter. Print the file with the IGP/PGL program. The debug parameter lists the program, line by line (including the error on the line where the error occurs), followed by the error±free sections of the form. Correct the error and print the file again. When the error has been corrected, delete the debug parameter.

For example, assume you made two errors in the Box and Corner commands input in steps 3 and 4 of the Form and Bar Code Example on page 6±19. Using the debug parameter in the Create command produces the following sample listing:

/PRACTICE BOX 2;35;16:53;61

***ERROR 24 : BOX format or delimiter error in input parameters

STOP CORNER 3;300;13;57;64;5;7

***ERROR 35 : CORNER vertical length VL out of bounds

***ERROR 31 : CORNER starting row SR out of bounds

***ERROR 39 : CORNER starting row SR > ending row ER STOP
