A slow day today so here is a revised itest command with provisional
|
||||
support for comparing strings as well :-))
|
||||
|
||||
Now table driven to allow the operators
|
||||
-eq, -ne, -lt, -gt, -le, -ge, ==, !=, <>, <, >, <=, >=
|
||||
|
||||
Uses the expected command modifier for integer compares of width 1, 2 or
|
||||
4 bytes of .b, .w, .l and the new modifer of .s for a string compare.
|
||||
String comparison is over the length of the shorter, this hopefully
|
||||
avoids missing terminators when using an indirect pointer.
|
||||
|
||||
eg.
|
||||
if itest.l *40000 == 12345678 then; ....
|
||||
if itest.w *40000 != 1234 then; ....
|
||||
if itest.b *40000 >= 12 then; ....
|
||||
if itest.s *40000 -eq hello then; ....
