Use of <strong>the</strong> letter P is required in all programs assembled on an <strong>1130</strong> or 1800 system, or using<strong>the</strong> standalone assembler. The P is optional for o<strong>the</strong>r use except for <strong>the</strong> PREP instruction,where it is required.2. Available only with model Exx.3. These instructions are not supported by <strong>the</strong> <strong>System</strong>/7 Standalone Assembler or for <strong>System</strong>/7programs assembled on an <strong>1130</strong> or 1800 system.4. The system treats <strong>the</strong>se instructions as I/0 instructions. Therefore, interface delay times cause<strong>the</strong> range of execution times.5. An X may be substituted for <strong>the</strong> P in this instruction.6. 0, <strong>the</strong> delay inherent in a system configuration, varies from 100 to 2100 ns depending on <strong>the</strong>physical location of <strong>the</strong> I/O module concerned. D varies from 100 to 800 ns on systems withouta 5026 Enclosure Model D3 or D6.Figure 4-1. (Part 2 of 2) <strong>System</strong>/7 Instructions111111111,1111 1 IIi<strong>All</strong>iii IIon Fp
