Hi,

i wanted to know the method of getting the length of a field entered by the user on an online screen.
For eg.
i want the user to enter 6 digits mandatory in the field. I have done the validation for numerics..but i am unable to force the user to enter 6 digits...
Can we use the lenght function on the input field?


any help will be greatly appreciated.
Thanks

DCL IN_STR CHAR(6); /* This will limit the length to NO MORE than 6 chars */

[...your code here...]

IF INDEX(IN_STR, " ")> 0 THEN DO;
/* If there's a space, there's definitely a problem. Enter code to process */
END;

/* Enter code for other validation steps */
