Actually, it might be needed to avoid premature termination at an
empty record.
OK. Suppose the OP is 100.00% certain that his data contain no empty
records (is he willing to test for this condition and report it as an error?)
But code snippets have a tendency to be recycled far beyond their
original intended purpose. Strive for generality, even needless generality.
similarly:
...
>>> if thisword='' then leave
>>>
The "=" operator is a fuzzy comparison. It will match if thisword contains
any number of blanks and nothing else. Better to use "==" even if he's
certain that his data contain no blank lines.
So:
...
do t = 1
if MyArg == '' then leave t
parse var MyArg outstem.t ';' MyArg
outstem.t = Left(oustem.t,80) /* Or should >80 be reported as an
error? */
end t
outstem.0 = t-1
Say 'Number of lines written: 'outstem.0
"ALLOC DA('"dsnname"') F(Pdsout) OLD REUSE"
"EXECIO" outstem.0 "DISKW Pdsout (STEM outstem. FINIS"
"FREE F(Pdsout)"
Return
This leaves a nonuniformity; a lurking astonishment factor. If the last
record is empty and not followed by a ";" it will be written unless it is
empty, in which case it will not be written.
