Hello Gurus,

My code:
Code:
x = listdsi("'QX000241.JCL.PS'")

works well. x comes out as 0.

but my code:

Code:
env = 'JCL'
es62b = 'PS'
backupdsn = '"'||"'"||'QX000241.'||env||'.'||es62b||"'"||'"'
x = listdsi(backupdsn)         


fails with 16 (though backupdsn on print looks exactly like below)
Code:
 "'QX000241.JCL.PS'"


Could you please help?

Gurus,
It works if I include the code as below:

backupdsn = "'QX000241."env"."es62b"'"

On print it looks as:
'QX000241.JCL.PS'

I would add a space function just in case there are leading or trailing blanks in env or es62b.
Code:

backupdsn = space("'QX000241."env"."es62b"'",0)

I do not know of a SPACE function in Rexx - you are probably thinking of STRIP

On print it should look like
Code:
'QX000241.JCL.PS'

Code:
/* rexx */                                               
env = 'JCL'                                               
es62b = 'PS'                                             
backupdsn = space("'QX000241."  env "." es62b "'",0) 
x = listdsi(backupdsn)                             
return                                                   

As suggested works for me
