-A port of PDCurses must provide acs_map[], a 128-element array of 
-chtypes, with values laid out based on the Alternate Character Set of 
-the VT100 (see curses.h). PDC_transform_line() must use this table; when 
-it encounters a chtype with the A_ALTCHARSET flag set, and an A_CHARTEXT 
-value in the range 0-127, it must render it using the A_CHARTEXT portion 
-of the corresponding value from this table, instead of the original 
-value. Also, values may be read from this table by apps, and passed 
-through functions such as waddch(), which does no special processing on 
-control characters (0-31 and 127) when the A_ALTCHARSET flag is set. 
-Thus, any control characters used in acs_map[] should also have the 
-A_ALTCHARSET flag set. Implementations should provide suitable values 
-for all the ACS_ macros defined in curses.h; other values in the table 
-should be filled with their own indices (e.g., acs_map['E'] == 'E'). The

+A port of PDCurses must provide acs_map[], a 128-element array of
+chtypes, with values laid out based on the Alternate Character Set of
+the VT100 (see curses.h). PDC_transform_line() must use this table; when
+it encounters a chtype with the A_ALTCHARSET flag set, and an A_CHARTEXT
+value in the range 0-127, it must render it using the A_CHARTEXT portion
+of the corresponding value from this table, instead of the original
+value. Also, values may be read from this table by apps, and passed
+through functions such as waddch(), which does no special processing on
+control characters (0-31 and 127) when the A_ALTCHARSET flag is set.
+Thus, any control characters used in acs_map[] should also have the
+A_ALTCHARSET flag set. Implementations should provide suitable values
+for all the ACS_ macros defined in curses.h; other values in the table
+should be filled with their own indices (e.g., acs_map['E'] == 'E'). The
+table can be either hardwired, or filled by PDC_scr_open(). Existing
 ports define it in pdcdisp.c, but this is not required.
