Form Examples and Exercises 6–50
From the description of the error messages and the incorrect line identified
by the error message, the errors are easily located and corrected. Notice a
colon was accidentally input in the Box command where a semicolon was
required (error number 24).
/PRACTICE
BOX
2;35;16:53;61
*** ERROR 24 : BOX format or delimiter error in input parameters
STOP
In the Corner command, the starting row was too large. This single input
error caused the vertical length of the corner to extend beyond the form
boundaries (error number 35), the starting row to begin outside the form
boundaries (error number 31), and the starting/ending row parameters to be
out of order (error number 39).
