I need to insert values to DB file. For that, I have created 2 rpg/400 programs(rpg(A),rpg(B)) and I'm receiving values from user through screen- this concept is there in RPG(A) program and by calling RPG(B) from RPG(A). I'm doing insert operation in that DB file - this concept is there in RPG(B) program. Now DB file is not getting populated so I have to find out the solution by debugging the RPG(B) program.(bcoz insert part is there in RPG(B) ) but if I try to debug RPG(B) I got a message '' ERROR RPG0221 CAUSED PROGRAM RPG(B) TO STOP'', since no values received for that input fields.because the screen is connected with rpg(A). So I tried to give values for that variable manually in eval operation. That time it shows message like"identifer does not exist"means, this input field could not be recognized by RPG(B) program..so please tell me what should I do now?
