TRCREF Command (Traditional)

The TRCREF command specifies the relationship between a font and a table-reference character (TRC) in the data. When specified, the TRCREF command must immediately follow a PAGEFORMAT command.

TRCREF

Specifies the TRC numbers that can appear in print data.

n

The allowable values are 0 to 126; each TRCREF command must contain a unique number within a page format.

If n is omitted, PPFA automatically adds one to the n value of the previous TRCREF command in the sequence and assigns that value.

The default for the first TRCREF command is 0.

Depending on the value specified for n, the TRC is interpreted by the print server as being either compatible or incompatible with S/370 1403 line-mode. Notice that, if compatibility TRCs are to be used, no fonts should be specified in any PRINTLINE or FIELD commands within the same PAGEFORMAT.

0–3

Indicate a compatible TRC for a S/370 1403 line-mode data stream

4–126

Indicate an incompatible TRC for a S/370 1403 line-mode data stream

Also notice that any TRC number outside the range of 0–3 results in non-compatibility TRCs for the entire page definition. If compatibility TRCs are used, do not specify fonts on PRINTLINE or FIELD commands within the same PAGEFORMAT.

Note:
1. You can have multiple TRCs pointing to the same font.
2. If 4 or fewer fonts are specified, they are treated as compatibility TRCs and the leftmost 4 bits of the TRC are ignored. For example, in this case X'F0' and X'00' are both valid for TRC0.
