Having received error reports from users of BSF4ooRexx like
2 *-* /**/@
Error 13 running
rexx_invoked_via_[fxml_01.fxml]_at_2020_08_05T12_33_24_17Z.rex line 2: Invalid
character in program.
Error 13.1: Incorrect character in program "@" ('40'X).
and looking up the execution paths in those cases, it turns out that the ooRexx
.routine class gets
used to create the executable in those cases with a string array representing
the compiled and
encoded Rexx program.
So the "new" method of the .routine class gets the compiled and encoded source
supplied as an array
of strings, e.g.:
#!/usr/bin/env rexx
/**/@REXX@
LyoqL0BSRVhYAAAAAAAAAGcrKgAgAAAAVOwAAAAAAABwEgAAVPq7VhgAAAACAAAAAAAAAAAA
AAAAAAAAgB68ViAAAAACAAAAKAAAAAAAAABwAAAAOAAAAAAAAADkSrxWOAAAAAIAAAAFAACA
... cut ...
Supplying the compiled and encoded data as a single string to the .routine
class does not work as
this issues the error "13.1, Invalid character in program" caused by the
presence of a LF ('0A'x)
character, here a rexxtry example:
infile=.stream~new("nutshell_01.rex-compiled")~~open("read")
........................................... rexxtry.rex on WindowsNT
pgm=infile~charin(infile~chars)
........................................... rexxtry.rex on WindowsNT
infile~close
........................................... rexxtry.rex on WindowsNT
r1=.routine~new("aha",pgm)
Oooops ! ... try again. Invalid character in program.
Incorrect character in program "
" ('0A'X).
rc = 13.1 ................................. rexxtry.rex on WindowsNT
As a compiled and encoded form of a Rexx program always has the string
"/**/@REXX@" as the value for
its second line it would be possible to determine that the String array comes
from a compiled and
encoded Rexx program. Rather than creating an error in this case, the routine
object could get
created successfully from the String array representing a compiled and encoded
Rexx program.
Are there any objections to try to enhance the "new" method of the .routine
(and the .method) class
such that the string array can represent a compiled and encoded Rexx program?
