About This Manual
The Portable Transaction Application Language for HP NonStop systems (pTAL) is a

oriented applications.
This manual gives guidelines for using the pTAL language and the EpTAL and pTAL
compilers, including:
•
How to create, structure, compile, and run a pTAL program
•
The process environment, addressing modes, and storage allocation
•

You can compile pTAL source programs with either the pTAL compiler or the EpTAL
compiler (for their differences, see Table 1-1 on page 1-2).
