High Quality Content by WIKIPEDIA articles! STRETCH Assembly Program (STRAP) was the assembler for the IBM 7030 Stretch computer. The first version (STRAP-1) was a subset cross assembler that ran on the IBM 704, IBM 709, and IBM 7090 computers. The final version (STRAP-2) ran natively. A program written in assembly language consists of a series of instructions--mnemonics that correspond to a stream of executable instructions, when translated by an assembler, that can be loaded into memory and executed.
