String Concatenation

This module provides functions for concatenation of strings, and the name CharPtr for the type char *.

The module is instantiated by

   $/Tech/Strings.specs

All entities exported by this module can be used in specifications of type .lido, .init, .finl, and .con. They can also be used in .pdl specifications or in C modules if the interface file Strings.h is imported there.

The module defines the type name CharPtr for char *, especially to be used in LIDO specifications.

The module exports the functions

CharPtr CatStrStr (CharPtr s1, CharPtr s2)
The strings s1, s2 are concatenated. The resulting string is stored in the string memory of the csm module, and the pointer to it is returned.

int IndCatStrStr (CharPtr s1, CharPtr s2)
The strings s1, s2 are concatenated. The resulting string is stored in the string memory of the csm module, and its StringTable index is returned.

A macro CatStrInd(s,i) is exported it obtains the second of the concatenated strings by the index i into the StringTable. This macro is used to simplify composition of message texts.
