Hi all,
Can anybody please tell me why my this program is not getting executed.
***************************** Top of Data ******************************
/*REXX*/
/* REXX SHOWING UNTIL/WHILE LOOPS*/
A = 6; B = 1; C = 1
DO WHILE A \= B
SAY "B= " B
B = B + 1 ;
END
DO UNTIL A = C
SAY "C= " C
C = C + 1 ;
END
**************************** Bottom of Data ****************************


I'm getting error:

4 +++ DO WHILE A :
IRX0013I Error running SSS, line 4: Invalid character in program
***

actually i'm getting problem in using the "NOT EQUAL TO" operator. I'm using this "\" operator. but its not working.
If anyone can give me the proper key for "not equal to" it 'll be very helpful for me.

The error message says that the Rexx interpreter thinks that you have a colon (:) after your A. To find what the 'not' operator is you have access to manuals including the Rexx Language Reference. That information is in there. Do not connfuse what might be legal on the PC with what might be legal on the mainframe. To be portable you should use <>. Ususally on the mainframe you use the symbol usually found on the top of the top left key - accessed via Alt Gr in Windoze.

And, please do not colour code your posts - using the full editor you can highlight your code and click the 'Code' button. This will preserve spacing and give you a nice blue on black presentation like this..

See "TSO/E REXX Reference" for your release.

Hi,

Hi Enrico,
it worked... thanks. I was problem in using the not operator.

The ¬ character is not well defined in ASCII. Most of the time the ^ character (Shift-6 in PC keyboards) will become the EBCDIC ¬ character when entered through most 3270 emulators.
