6–49 Form Examples and Exercises
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 “Error
Codes” chapter.
To solve program errors, perform the following steps:
1. Locate the error message in the listing provided in the “Error Codes”
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
