TEST—CALL subcommand

Use the CALL subcommand to initiate processing at a specified address and to initialize registers 1, 14, and 15. You can pass parameters to the program that is to be tested.

CAUTION:

The contents of registers 1, 14, and 15 are altered by the use of the CALL subcommand. To save the contents of these registers, use the COPY subcommand of TEST (see Example 2 and Example 3 under TEST—COPY subcommand).

The CALL subcommand of TEST places the return address of the tested program in register 14. The high-order bit of register 14 is set to reflect the addressing mode of the tested program.
