cliu 83af63ab53 R1.05 re-check batch 2: graphics, history, portal, system-management, items 
Full manual diffs (C50, R30, C60, L20, C40, L35, R10, R20, J10, L30, L50,
P30, G10, C10) and read-only checks on the shared R1.05 test server where
the permission system allowed them. Skills and summaries moved to R1.05.
Issues ISS-092..129 (gaps 104-107, 114-115, 130-131 unused); ISS-074
closed (manual and software agree), ISS-091 corrected by ISS-119.
version-differences: unlisted manual changes and installed-only changes.
r105-verification: V5-V9 and new not-tested rows.

task: String items: length limit and truncation version: R1.05 (first written for R1.03) source: IM 36K10C10-01EN 5th ed. (Feb. 2026) §3.3.4; IM 36K10G10-01EN 5th ed. (Feb. 2026) §3.2.2; data dictionary (dssqld -f); practiced on CI-Eng-Sample 2026-09-30 (R1.03) status: verified on R1.03 (2026-09-30); on R1.05 the limit 1–200 / default 80 was checked in the data dictionary and ITEM_DF is identical (2026-10-08, read-only); string writes and truncation not re-tested on the shared R1.05 test server, re-test awaits a decision (ISS-129)

String items

A string item has a maximum length set when it is created (ITEM_DF.STRING_LENGTH).

Rule Value (verified R1.03)
Allowed STRING_LENGTH 1–200 (default 80); 201 is rejected with DSS-E-VAL_RANGE
Audit trailing (AUDIT_INFO) no effect on the limit (200 loads with audit on)
Characters the item holds length − 1 (length 100 holds 99)
Value that fits stored, status 9 NORMAL
Value too long cut to length − 1, status 12 OVERRANGED, no error from itmval

The R1.03 manuals disagreed (Engineering Module: max 100; Tutorial: 168; ISS-019). The R1.05 manuals (changed in R1.04, not listed in the revision tables) give default 80 and maximum 200 bytes, matching the software (ISS-124). Multi-byte characters take more than one byte. That a value holds only length − 1 characters is not in any manual.

Quick load (the section must exist):

@FIELDS
NAME,DESCRIPTION,ITEM_REP,STRING_LENGTH,AUDIT_INFO

@ITEM_DF
"<Section>.<Tag>","Status text","String",120,0

Write and read: itmval -p -n <Section>.<Tag> -v "text", itmval -g -n <Section>.<Tag>. After a write, check the status: 12 means the text was cut.

The representation (type) and length cannot be changed on an existing item: remove and load it again.
