Dictionary Files
The dictionary stores all of the text items associated with each statement in a text file.
Each text item is uniquely identified by a text ID number. A single text item can consist
of a list of several lines of text; the list is ordered by element number.
Table D-1 on page D-3 shows the text items described in the following three objects:
CONSTANT custnum-heading VALUE "Customer".
DEF initials PIC XXX VALUE ALL SPACES
HELP "Initials".
DEF quantity PIC 999 MUST BE 1 THRU 999.
In Table D-1 on page D-3, each text item is assigned a unique text ID number. A single
text item can contain more than one text type.
