pTAL Reference Manual (G06.24+, H06.09+, J06.03+)

About This Document
The Portable Transaction Application Language for HP NonStop systems (pTAL) is a high-level,
block-structured language used to write systems software and transaction-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
• How to declare and access procedures and variables
You can compile pTAL source programs with either the pTAL compiler or the EpTAL compiler (for
their differences, see Figure 16 (page 361)).
