What is the Null Character to GPC for use in CHARs and STRINGs? In my previopus compiler \00 was used for this.
VAR a : array [1..4] of chars; b : array [1..4] of chars; c : array [1..4] of chars; d : array [1..4] of chars;
BEGIN
a = '\00\00\00\00'; FILLCHAR(b, 4, CHR(0)); c ='0000'; d = '';
None of these are equivalent (I would expect the last two to not be equivalent). Basically, I am just looking for a way to test if an array of chars has been zeroed out using FILLCHAR with chr(0). Also, with GPC, when a new variable is defined, is it automatically zeroed out?
Thanks! Adam Oldham
