Comments on the table

¹For the FOR1 V2.2C compiler, ILCS capability is set using the compiler option:

• If the program unit was compiled with the compiler option
  COMOPT LINKAGE=FOR1-SPECIFIC, then COMP=FOR1 must be specified in the PROGRAM statement. This compiler option specifies that the program uses the “old” FOR1 interface.

• If the program unit was compiled with the compiler option COMOPT LINKAGE=STD (default value), then COMP=ILCS must be specified in the PROGRAM statement. compiler option specifies that the program uses the ILCS interface.

Notes on mixing languages

A UTM application may contain FOR1 program units that have been entered in the configuration with different values for PROGRAM ...,COMP= . In this manner, program units can co-exist in a UTM application where one program unit uses the “old” FOR1 interface and another uses the ILCS interface.
