I tried a simple program. But I got the follwing error message after giving the two numbers as input.
7 +++ SM = NUMBER1 + NUMBER2
IRX0041I Error running ADDITION, line 7: Bad arithmetic conversion
***
Code is
| Code: |
/* REXX */
/* THIS EXEC ADDS TWO NUMBERS AND DISPLAYS THEIR SUM. */
SAY 'PLEASE ENTER A NUMBER.'
PULL NUMBER1
SAY 'NOW ENTER A NUMBER TO ADD TO THE FIRST NUMBER.'
PULL NUMBER2
SM = NUMBER1 + NUMBER2
SAY 'THE SUM OF THE TWO NUMBERS IS' SM'.' |
Please clarify me. |

Please post the TRACE output from a real-time run. Thanks.
One of the two values entered is NOT numeric. You might want to add a check to validate their format first. |

Kevin,
I have included TRACE in the code. And I come to know that NUMBER2 is not getting value from terminal, ie, NUMBER2 is null string. So, it causes bad arithmetic conversion.
Modified code is
| Code: |
/* REXX */
/* THIS EXEC ADDS TWO NUMBERS AND DISPLAYS THEIR SUM. */
SAY 'PLEASE ENTER A NUMBER.'
PULL NUMBER1
SAY 'NOW ENTER A NUMBER TO ADD TO THE FIRST NUMBER.'
PULL NUMBER2
TRACE I
SM = NUMBER1 + NUMBER2
SAY 'THE SUM OF THE TWO NUMBERS IS' SM'.' |
The input given is
PLEASE ENTER A NUMBER.
12
NOW ENTER A NUMBER TO ADD TO THE FIRST NUMBER.
*** 3
Why that *** is coming while giving NUMBER2(marked in blue color)?
The output is
8 *-* SM = NUMBER1 + NUMBER2
>V> "12"
>V> ""
8 +++ SM = NUMBER1 + NUMBER2
IRX0041I Error running ADDITION, line 8: Bad arithmetic conversion
***
How to resolve this? |

| *** is what you usually see when you screen is full and you need to hit enter before entering any data. |

gnanas,
Hit enter after *** and check. In my training, i was told to hit enter whenever *** comes up in the terminal.
Else try getting both the values in a single PULL statement like PULL VAR1 VAR2. |
