I am generating the jcl using file tailoring. The skeleton jcl uses the temporary dataset &&dataset1 which get converted to &dataset1 in the generated jcl.

&& gets converted to &

Code:
ORIGINAL CODE:                                   
//OUTFILE  DD DSN=&&DATASET1,DISP=(NEW,PASS,DELETE)
                                                 
CONVERTED CODE:                                   
//OUTFILE  DD DSN=&DATASET1,DISP=(NEW,PASS,DELETE)


Please advice.

1) JCL rule: both &&DATASET, and &DATASET are considered as the same temporary DSNAME

2) File Tailoring rule: in order to generate each single apostrophe, two '&' characters in a row must be used:
'&&' --> '&'
'&&&&' --> '&&'

Unless there is a SET symbol (or system symbol if activated for batch jobs) with that name, so I would advocate always using double ampersands for temporary datasetnames.
