A string containing an unmatched apostrophe. It's been a long time;
I can only re-create with a pointless example. Here's my REXX exec:
/* REXX Useful! */ interpret arg(1)
And it was in an ISPSTART context; something like:
ispstart cmd( exec 'user.clist(rexx)' 'say arg( 1 ); exit; ''' )
which prints:
READY
ispstart cmd( exec 'user.clist(rexx)' 'say arg( 1 ); exit; ''' )
say arg( 1 ); exit; '
***
Note the single apostrophe in the output. I don't remember why I
needed that apostrophe (or something similar), but I can get it with
EXEC, not with '%'
