Known issues and workarounds
____________________________________
A. Installing 4GL and CSDK into same folder can result in issues with
4GL at runtime, check the machine notes for platform specific
issues and CSDK versions.
Workaround :
It is highly recommended that 4GL and CSDK/IDS be installed into
separate folders.
B. Statements inside SQL blocks duplicates the first character of a string that
starts with an hypen.
For Example :
MAIN
SQL
UPDATE tab
SET col1= col1* -2 WHERE key="key"
END SQL
Both 4GL pcode compiler and C compiler generate wrong code for the above SQL statement,
for given example above generated 4ec files will have following statement
update tab set col1 = col1 * - 22 WHERE key = "key"
Correct translation should be 'col1 * - 2' but generated code is 'col1 * - 22', this
happens for all SQL that has 'hypen' inside the SQL..END SQL block.
Workaround :
If you have any SQL with hyphen then do not put it inside the SQL... END SQL block.
