(tu30.txt)
Tutorial tu3 is concerned with the tools available to add J-code to the J-lib.
The main verb used for this purpose is named filecode y. 
Input y. is a list of verb names to be filed. This list contains the names 
seperated by 1 blank space.
The verb processes each name by referring to the information contained 
in the result of verb: r=.disp "name". This implies that the verb to be filed
has to be present in the session-space while filecode is active.
The filing results for each name is recorded in the following files:
TMP0 - ERROR: unknown (verb) type: 
TMP1 - No filing required: (0=$r)  (TMP1 is not used: obsolete)
TMP2 - Abort due to error:(1=$r) 
TMP3 - Names filed:(1<$r) 
TMP4 - (tacit or :20) use special files 
TMP5 - (:0) use special files
