Parrot - Operations
There are a variety of operations you can perform. For instance, we can print out the contents of a register or a constant:
set I1, 10 print "The contents of register I1 is: " print I1 print "\n"
The above instructions will result in The contents of register I1 is: 10
We can perform mathematical operations on registers:
# Add the contents of I2 to the contents of I1 add I1, I1, I2 # Multiply I2 by I4 and store in I3 mul I3, I2, I4 # Increment I1 by one inc I1 # Decrement N3 by 1.5 dec N3, 1.5
We can even perform some simple string manipulation:
set S1, "fish" set S2, "bone" concat S1, S2 # S1 is now "fishbone" set S3, "w" substr S4, S1, 1, 7 concat S3, S4 # S3 is now "wishbone" length I1, S3 # I1 is now 8
