System Interaction Variables

The system variables in INTERACTION statements allow the end-user to override values assigned to system variables in the DF2 file.

For instance, a DF2 parameter specifies the start number for sequencing. That parameter initializes the system variable SEQ_START. By defining SEQ_START in an INTERACTION statement, the end-user gets the ability to change the sequencing start value at runtime.

When using system variables in INTERACTION statements, no initialization value is allowed. The initial value for these system variables only comes from the DF2 file.

When using system variables in INTERACTION statements, the format parameter does not change the system variable format. It is only used if MULTI_CHOICE or BOOLEAN_ are specified, in which case the interaction takes a special form (as explained below). The specified format argument must "match" the system variable format - they must both be of type string (format CHARACTER) or type numeric (all other formats).
