Using the TSQL Shell6.1.4 TSQL Shell HelpFor shell help, type:• ? — for general help on using the shell.• ?SET — for help on settings.• ?EXT — for help on Caché extensions to TSQL.• ?BUF — for help on the simple buffer-editing facilities of the shell.6.1.5 Exiting the TSQL ShellTo exit the TSQL shell, type ^ at the terminal prompt.6.2 Qualifiers/c and /xIn its simplest form, ending a line of code with /c tells the TSQL shell to compile the TSQLcode. Ending a line of code with /x tells the TSQL shell to compile and execute the TSQLcode. However, ending a line with /c or /x can mean several different things, depending onwhether the code being compiled is a CREATE PROCEDURE or not, and whether thetarget is TSQL or Caché ObjectScript. The useful settings are given below:/cTarget = COS/cTarget = TSQL/xTarget = COS/xTarget = TSQLCREATE PROCwrites ObjectScript methodwrites TSQL methodn/an/anot CREATE PROCcompile MAC to INTn/acompile MAC to INT and executeINTn/a48 Caché Transact-SQL (TSQL) Migration Guide
If no CREATE PROCEDURE is given, the code is compiled to a temporary routine. IfCREATE PROCEDURE is given, the code is compiled to a class method.Writing a Caché ObjectScript method using /c on procedure code isn't useful in the usualway, in that you don't generally want ObjectScript methods, you want TSQL ones that youcan compile in Studio. However, it is a useful technique in the early stages of a project usingthe batch loader because you can quickly test-compile many stored procedures and get adetailed log of the results./tThe code-generation target defaults to "COS" in the shell. To set it to "TSQL" (for the nextcompilation only) type this:tsql/tSettings6.3 SettingsSettings are a Caché TSQL extension used to tailor the behavior of the compiler and colorizer.Each setting has a name and an abbreviation, as in GENRAW/GR. Either form may be used.Persistent settings are associated with the shell, and are stored in ^%TSQL("SETTINGS").You can set them in the TSQL shell using the = command. You can set a single setting, or acomma-separated list of settings. Issuing an = command deletes all previous settings. To resetall settings to defaults specify just the = command.A boolean flag setting can be set to a value either by assignment (for example, =CIC=1), orby just naming the setting (=CIC, which is equivalent to =CIC=1). You can turn off a flagsetting by setting it to 0 (=CIC=0).A string or integer setting is set to a value using assignment (for example, =SM='LOGICAL').You can revert to the default setting by assigning an empty string (=SM='').The shell command ?SET lists the available settings. For further details on these settings,refer to the Commands chapter.There is also a Caché TSQL extension command called SETTINGS which can be used tocontrol local settings. For further details, refer to the Commands chapter.^%SYS("tsql","defaultsettings")Holds system-wide default TSQL settings.Caché Transact-SQL (TSQL) Migration Guide 49
