Can anyone explain this phenomenon: Given this little program
Parse Version v Say v fid='' Say lines(fid) l=linein(fid) ll=length(l) If ll<>81 Then Say 'incorrect input' Say 'length(l)='ll Say 'garbage 1' /* comment */ Say 'garbage 2' Say 'garbage 3' Say 'garbage 4' Say 'garbage 5' Running it shows this output (after one presses Enter F:\>rexx sda REXX-ooRexx_5.0.0(MT)_64-bit 6.05 8 Sep 2020 0 incorrect input length(l)=0 garbage 1 garbage 2 garbage 3 garbage 4 garbage 5 How does the PROGRAM SOURCE find its way to the screen? Surprised, no: astonished: Walter BTW Regina shows 1 (not 0) as value of lines(). Otherwise the same behavior
