C/C++ Programmer's Guide (G06.27+, H06.08+, J06.03+)

You can declare pTAL-only, or C-only routine identifiers and satisfy both compilers by using the
public name option in:
• Interface declarations in C
• EXTERNAL procedure declarations in pTAL
In G-series Inspect or H-series Native Inspect sessions:
• Use uppercase for pTAL identifiers
• Use the given case for C identifiers
Matching Data Types
Use data types that are compatible between languages for:
• Shared global variables
• Formal or actual parameters
• Function return values
