!i and !o In procedure calls, the !i notation follows an input parameter (one that passes data to
the called procedure); the !o notation follows an output parameter (one that returns
data to the calling program). For example:
CALL CHECKRESIZESEGMENT (
segment-id
!i
,
error
) ; !o
!i,o In procedure calls, the !i,o notation follows an input/output parameter (one that both
passes data to the called procedure and returns data to the calling program). For
example:
error
:= COMPRESSEDIT (
filenum
) ; !i,o
!i:i In procedure calls, the !i:i notation follows an input string parameter that has a
corresponding parameter specifying the length of the string in bytes. For example:
error
:= FILENAME_COMPARE_ (
filename1
:
length
!i:i
,
filename2
:
length
) ; !i:i
!o:i In procedure calls, the !o:i notation follows an output buffer parameter that has a
corresponding input parameter specifying the maximum length of the output buffer in
bytes. For example:
error
:= FILE_GETINFO_ (
filenum
!i
, [
filename
:
maxlen
] ) ; !o:i
