EpTAL, pTAL, and TAL Compilers

You can compile pTAL source programs using either the pTAL compiler or the EpTAL

compiler.

Difference between pTAL and EpTAL compilers:

The compilers in Table 1-1 on page 1-2 execute under control of the HP NonStop

operating systems in Table 1-2 on page 1-2.

This manual indicates when pTAL behaves differently on TNS/E and TNS/R

architectures. When no architecture is specifically mentioned, the syntax works the

same way on TNS/E and TNS/R architectures.

Note. This topic includes only enough information about the TAL compiler to compare it to the

EpTAL and pTAL compilers. For complete information about the TAL compiler, see:
