!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
