Description Shift the source accumulator string src (or its offset) left one bit and store the
result in destination accumulator string (or its offset). Each accumulator is
shifted individually. The shifted bit is propagated through consecutive
accumulators in the string.
Example 4.14.68.1 SHLACS A1~, A1
Shift accumulator string A1 one bit to the left, store the result in accumulator string A1~. Note that this
instruction alters the content of all accumulators in the string.
