Answer Posted / senthil kumar m
TRT is used to scan a string of characters, searching
for the occurrence of any the characters which are
specified in a translate table.
TRT also sets the condition code to indicate the results
of the scanning operation as follows:
Condition Code Indications
0 ( Zero ) All function bytes
encountered were X’00’.
1 ( Minus ) A nonzero function byte
was found before the end of operand 1
2 ( Positive ) A nonzero function byte
was found at the end of the operand 1
The condition code can be tested using BZ, BNZ, BM, BNM,
BP, or BNP.
