Bar (unit) (symbol: cbar), and millibar (symbol: mbar or mb). The notation bar(g), though deprecated by various bodies, represents gauge pressure, i.e., pressure in bars above ambient or atmospheric pressure. The bar is defined using the SI derived unit, pascal: ≡ 100,000 Pa ≡ 100,000 N/m. Thus, is equal to: and 1 bar is approximately equal to: Notes: The word "bar" has its origin in the Greek word (), meaning weight. The unit's official symbol is bar; the earlier symbol b is now deprecated and conflicts with the use of b denoting the unit barn, but it is still encountered, especially as
Comparison of Object Pascal and C (if it has to be), i.e., its storage management is handled by the compiler (or more accurately, by the runtime code inserted by the compiler in the executable). String concatenation is done with the codice_65 operator, and string comparison can be done with standard relational operators (case sensitive): codice_66. Object Pascal also provides C-compatible strings under the type codice_67, with manipulation routines defined in the codice_68 unit. Moreover, Object Pascal provides a wide variety of string types: For convenience, the plain codice_76 type is provided, which, depending on a compiler switch, could mean codice_69, codice_71 or codice_74. An additional convention
