Pcode Opcode Meanings
Imp=import
Ad = Address

I2 = Integer

Anyone want to finish the list? I found these on this forum.

Prefixes:
Lit=Literal(ie "Hi",2,8 )
Imp=Import
St=Store
Ld=Load

Variable types:
I2=Integer
Cy=Currency
R4=
R8=Single
Str=String

Other:
DOC=Duplicate/Redundante Opcode(in the table it will redirect you to another opcode)


Golem could probably help most with these...i will edit this post later though.

for now you can look at pcode/opcodes.php?t=1

some of them have descriptions...you are welcome to comment on specific opcodes in the Pcode forum

The "R" series stands for "Real", as in a "real number"; used by the floating-point co-processor. The digit after the R is the length so the co-proc knows how to push or pop the data.
The "I" series uses the same convention.
Also, (as an FYI), VB classifies a byte as a 2-byte integer, but qualifies it with the "byte" descripton.
