The precompiler is compatible with precompilers that are ANSI SQL-89-compliant. However, you may have applications created with earlier Embedded SQL versions that are not ANSI-compliant. This precompiler uses most of the same Embedded SQL statements used in previous precompiler versions, but it processes them differently.
To migrate applications created for earlier precompiler versions:
Remove the following SQL statements and keywords from the application, because System 11 and later does not support them:
release connection_name
recompile
noparse
noproc
pcoptions sp_syntax
cancel
release causes a precompiler error; the precompiler ignores the other keywords. The cancel statement causes a runtime error.
Use the precompiler to precompile the application again.
