Re: Tokenizer error

[enztec]

Hi  Jürgen,

apl_command gives the exact same Tokenizer error as does apl_exec with )copy 
with the only difference being that apl_command does not output the usually apl 
command result output without assigning it to a variable and outputing it (or 
writeln/printf/printf directly)
)clear   CLEAR WS
)copy   DUMPED 2022-07-29  13:15:37 (GMT-6)

apl_exec(')copy /caf/rseq.seq');
DUMPED 2022-07-29  13:15:37 (GMT-6)

apl_command(')copy /caf/rseq.seq');
[no output]

var b : ansistring;
b := apl_command(')copy /caf/rseq.seq');
writeln(b);
DUMPED 2022-07-29  13:15:37 (GMT-6)

there is no difference between apl_command and apl_exec when working with 
)clear )copy )si )wsid etc in my code besides what is mentioned above

i tested the exact same code with python3 libapl and c libapl and get the exact 
same complete behaviors and times as with fpc libapl in all respects especially 
with the )copy behavior copying a ∇fns header)
(all require ⎕pw←0 in UCS_string.cc but python3 and c not requiring ⎕pw←80 in 
the main pgm before executing a )copy like fpc does)

---

if you look at the times below - libapl is the way i need to do my apl coding

when i run your code    (a,¨b)⌷¨⊂ar    1 time i get the following times in the 
stated various apl environments

in fns in apl ws   111 msec
in an apl executable script  110 msec
fpc executing apl script  110 msec

libapl c    59 msec
libapl python3 60 msec
libapl fpc  59 msec
